Background

After the Soviet Union (USSR) dissolved in 1991, the newly independent republics of Ukraine and Russia maintained ties. Ukraine agreed in 1994 to sign the Nuclear Non-Proliferation Treaty and dismantle the nuclear weapons in Ukraine left by the USSR. In return, Russia, the United Kingdom (UK), and the United States (US) agreed in the Budapest Memorandum to uphold the territorial integrity of Ukraine. In 1999, Russia signed the Charter for European Security, which "reaffirm dthe inherent right of each and every participating state to be free to choose or change its security arrangements, including treaties of alliance". After the Soviet Union collapsed, several former

In November 2013, Ukrainian president Viktor Yanukovych refused to sign an association agreement with the European Union (EU), overruling the Verkhovna Rada and instead choosing closer ties with the Russian-led Eurasian Economic Union.

Prelude and declaration of military operations

In March and April 2021, Russia began a major military build-up near the Russo-Ukrainian border. A second build-up followed from October 2021 to February 2022, in both Russia and Belarus. Members of the Russian government repeatedly denied having plans to invade or attack Ukraine; including government spokesman Dmitry Peskov on 28 November 2021, Deputy Foreign Minister Sergei Ryabkov on 19 January 2022, Russian ambassador to the US Anatoly Antonov on 20 February 2022, and Russian ambassador to the Czech Republic Alexander Zmeevsky on 23 February 2022. Putin's chief national security adviser, Nikolai Patrushev, believed that the West had been in an undeclared war with Russia for years. Russia's updated

strategy, published in May 2021, said that Russia may use "forceful methods" to "thwart or avert unfriendly actions that threaten the sovereignty and territorial integrity of the Russian Federation". Sources say the decision to invade Ukraine was made by Putin and a small group of war hawks in Putin's inner circle, including Patrushev and minister of defence Sergei Shoigu. During the second build-up, Russia demanded that the US and NATO enter into a legally binding arrangement preventing Ukraine from ever joining NATO, and remove multinational forces from NATO's Eastern European member states. Russia threatened an unspecified military response if NATO followed an "aggressive line". These demands were widely seen as non-viable; new NATO members in

had joined the alliance because they preferred the safety and economic opportunities offered by NATO and the EU, and their governments sought protection from Russian irredentism.

made respective efforts to prevent the war in February. Macron met with Putin but failed to convince him not to go forward with the attack. Scholz warned Putin about heavy sanctions that would be imposed should he invade Ukraine. Scholz, in trying to negotiate a settlement, also told Zelenskyy to renounce aspirations to join NATO and declare neutrality; however, Zelenskyy said Putin could not be trusted to uphold such an agreement. On 24 February, before 5:00 a.m. Kyiv time, Putin announced a "special military operation" in the country and "effectively declared war on Ukraine." In his speech, Putin said he had no plans to occupy Ukrainian territory and that he supported the right of the Ukrainian people to

Russian equipment and vehicles were marked with a white ''Z'' military symbol (a non- Cyrillic letter), believed to be a measure to prevent friendly fire.

Invasion and resistance

The invasion began at dawn of 24 February, with infantry divisions and armoured and air support in Eastern Ukraine, and dozens of missile attacks across both Eastern Ukraine and Western Ukraine. The first fighting took place in Luhansk Oblast near Milove village on the border with Russia at 3:40 am Kyiv time. The main infantry and tank attacks were launched in four spearhead incursions, creating a northern front launched towards Kyiv, a southern front originating in Crimea, a south-eastern front launched at the cities of Luhansk and Donbas, and an eastern front. Dozens of missile strikes across Ukraine reached as far west as Lviv. Wagner Group mercenaries and Chechen forces reportedly made several attempts to assassinate Volodymyr Zelenskyy. The Ukrainian government said these efforts were thwarted by anti-war officials in Russia's

(FSB), who shared intelligence of the plans. The Russian invasion was unexpectedly met by fierce Ukrainian resistance. In Kyiv, Russia failed to take the city as its attacks were repulsed at the suburbs during the battles of Irpin, Hostomel and Bucha. The Russian army tried to encircle the capital but Ukrainian forces managed to hold ground and put to effective use Western arms, including Javelin anti-tank missiles and Stinger anti-aircraft missiles, stretching thin Russian supply lines and stalling the offensive. On 9 March, a column of Russian tanks and armoured vehicles was ambushed in Brovary, suffered heavy losses and was forced to retreat. On the northern front, the Russian army adopted siege tactics to the key cities of Chernihiv, Sumy and Kharkiv but failed to capture them due to stiff resistance and logistical setbacks. On the southern front, Russian forces captured the major city of

was placed in charge of military operations during the invasion. On 18 April, retired Lieutenant General Douglas Lute, the former US ambassador to NATO, reported in a '' PBS NewsHour'' interview that Russia had repositioned its troops to initiate a new assault on Eastern Ukraine which would be limited to Russia's original deployment of 150,000 to 190,000 troops for the invasion, though the troops were being well supplied from adequate weapon stockpiles in Russia. For Lute, this contrasted sharply with the vast size of the Ukrainian conscription of all-male Ukrainian citizens between 16 and 60 years of age, but without adequate weapons in Ukraine's highly limited stockpiles of weapons.

in Germany to discuss forming a coalition to provide economic support and military supplies and refitting to Ukraine. Following Putin's Victory Day speech in early May, US Director of National Intelligence Avril Haines said no short term resolution to the invasion should be expected. Russian forces improved their focus on protecting their supply lines by advancing more slowly, and more methodically. They also benefited from centralising command under General Dvornikov. Ukraine's reliance on Western-supplied equipment constrained it, as Western countries feared that Ukraine would use it to strike targets in Russia. Military experts disagreed on the future of the conflict; some suggested Ukraine to trade territory for peace, while others assessed that Ukraine could sustain its resistance to the invasion, due to the Russian losses. On 26 May 2022, the Conflict Intelligence Team, citing Russian soldiers, reported that

Gennady Zhidko had been put in charge of Russian forces during the invasion, replacing Army General Dvornikov. By 30 May, disparities between Russian and Ukrainian artillery were apparent with Ukrainian artillery being vastly outgunned by range and number. In response to Biden's indication that enhanced artillery would be provided to Ukraine, Putin indicated that Russia would expand its invasion front to include new cities in Ukraine and in apparent retribution ordered a missile strike against Kyiv on 6 June after not directly attacking the city for several weeks. On 10 June 2022, Vadym Skibitsky, deputy head of Ukraine's military intelligence, stated during the Severodonetsk campaign that the frontlines were where the future of the invasion would be decided: "This is an artillery war now, and we are losing in terms of artillery.

, apparently to encircle the city from the west, supported by two separate axes of attack from Russia along the east bank of the Dnipro: the western at Chernihiv, and the eastern at Sumy. These were likely intended to encircle Kyiv from the north-east and east. Russia apparently tried to rapidly seize Kyiv, with Spetsnaz infiltrating into the city supported by airborne operations and a rapid mechanised advance from the north, but was unsuccessful. Russian forces advancing on Kyiv from Belarus gained control of the ghost towns of Chernobyl and Pripyat. Russian Airborne Forces attempted to seize two key airfields near Kyiv, launching an airborne assault on Antonov Airport, and a similar landing at Vasylkiv, near Vasylkiv Air Base, on 26 February. By early March, Russian advances along the west side of the Dnipro were limited by Ukrainian defences. As of 5 March, a large Russian convoy, reportedly long, had made little progress toward Kyiv. The London-based think tank Royal United Services Institute (RUSI) assessed Russian advances from the north and east as "stalled". Advances from Chernihiv largely halted as a siege began there. Russian forces continued to advance on Kyiv from the northwest, capturing Bucha, Hostomel, and Vorzel by 5 March, though Irpin remained contested as of 9 March. By 11 March, the lengthy convoy had largely dispersed and taken cover. On 16 March, Ukrainian forces began a counter-offensive to repel Russian forces. Unable to achieve a quick victory in Kyiv, Russian forces switched their strategy to indiscriminate bombing and siege warfare. On 25 March, a Ukrainian counter-offensive retook several towns to the east and west of Kyiv, including Makariv. Russian troops in the Bucha area retreated north at the end of March. Ukrainian forces entered the city on 1 April. Ukraine said it had recaptured the entire region around Kyiv, including Irpin, Bucha, and Hostomel, and uncovered evidence of war crimes in Bucha. On 6 April, NATO secretary-general Jens Stoltenberg said that the Russian "retraction, resupply, and redeployment" of their troops from the Kyiv area should be interpreted as an expansion of Putin's plans for Ukraine, by redeploying and concentrating his forces on Eastern Ukraine.

wrote that the Sumy axis was then "the most successful and dangerous Russian avenue of advance on Kyiv", and commented that the geography favoured mechanised advances as the terrain "is flat and sparsely populated, offering few good defensive positions". Travelling along highways, Russian forces reached Brovary, an eastern suburb of Kyiv, on 4 March. The Pentagon confirmed on 6 April that the Russian army had left Chernihiv Oblast, but Sumy Oblast remained contested. On 7 April, the governor of Sumy Oblast said that Russian troops were gone, but left behind rigged explosives and other hazards.

A third Russian attack group from Crimea moved northwest and captured bridges over the Dnieper. On 2 March, Russian troops won a battle at Kherson; this was the first major city to fall to Russian forces in the invasion. Russian troops moved on Mykolaiv, attacking it two days later. They were repelled by Ukrainian forces. On 2 March, Ukrainian forces initiated a counter-offensive on Horlivka, controlled by the DPR since 2014. After renewed missile attacks on 14 March in Mariupol, the Ukrainian government said more than 2,500 had died. By 18 March, Mariupol was completely encircled and fighting reached the city centre, hampering efforts to evacuate civilians. On 20 March, an art school sheltering around 400 people, was destroyed by Russian bombs. The Russians demanded surrender, and the Ukrainians refused. On 24 March, Russian forces entered central Mariupol. On 27 March, Ukrainian deputy prime minister Olha Stefanishyna said that "(m)ore than 85 percent of the whole town is destroyed." Putin told

in a phone call on 29 March that the bombardment of Mariupol would only end when the Ukrainians surrendered. On 1 April Russian troops refused safe passage into Mariupol to 50 buses sent by the United Nations to evacuate civilians, as peace talks continued in Istanbul. On 3 April, following the retreat of Russian forces from Kyiv, Russia expanded its attack on Southern Ukraine further west, with bombardment and strikes against Odesa, Mykolaiv, and the Zaporizhzhia Nuclear Power Plant.

Eastern front

Russian bombardment on the outskirts of Kharkiv

In the east, Russian troops attempted to capture Kharkiv, less than from the Russian border, and met strong Ukrainian resistance. On 25 February, the Millerovo air base was attacked by Ukrainian military forces with OTR-21 Tochka missiles, which according to Ukrainian officials, destroyed several

On 1 March, Denis Pushilin, head of the DPR, announced that DPR forces had almost completely surrounded the city of Volnovakha. On 2 March, Russian forces were repelled from Sievierodonetsk during an attack against the city. Izium was reportedly captured by Russian forces on 17 March, although fighting continued. On 25 March, the Russian defence ministry said it would seek to occupy major cities in Eastern Ukraine. On 31 March, the Ukrainian military confirmed Izium was under Russian control, and '' PBS News'' reported renewed shelling and missile attacks in Kharkiv, as bad or worse than before, as peace talks with Russia were to resume in Istanbul. Amid the heightened Russian shelling of Kharkiv on 31 March, Russia reported a helicopter strike against an oil supply depot approximately north of the border in Belgorod, and accused Ukraine of the attack. Ukraine denied responsibility. By 7 April, the renewed massing of Russian invasion troops and tank divisions around the towns of Izium, Sloviansk, and Kramatorsk prompted Ukrainian government officials to advise the remaining residents near the eastern border of Ukraine to evacuate to western Ukraine within 2–3 days, given the absence of arms and munitions previously promised to Ukraine by then.

Second phase: South-Eastern front (8 April – 5 September)

2022 Russian Invasion of Ukraine Phase 2 animated

By 17 April, Russian progress on the south-eastern front appeared to be impeded by opposing Ukrainian forces in the large, heavily fortified Azovstal steel mill and surrounding area in Mariupol. On 19 April, ''The New York Times'' confirmed that Russia had launched a renewed invasion front referred to as an "eastern assault" across a front extending from Kharkiv to Donetsk and Luhansk, with simultaneous missile attacks again directed at Kyiv in the north and Lviv in Western Ukraine. As of 30 April, a NATO official described Russian advances as "uneven" and "minor". An anonymous US Defence Official called the Russian offensive: "very tepid", "minimal at best", and "anaemic". In June 2022 the chief spokesman for the Ministry of Defence of the Russian Federation Igor Konashenkov revealed that Russian troops are divided between the Army Groups "Center" commanded by Colonel General Aleksander Lapin and "South" commanded by Army General

regions. Russian Ground Forces started recruiting volunteer battalions from the regions in June 2022 to create a new 3rd Army Corps within the Western Military District, with a planned strength estimated at 15,500–60,000 personnel. Its units were deployed to the front around the time of Ukraine's 9 September Kharkiv oblast counteroffensive, in time to join the Russian retreat, leaving behind tanks, infantry fighting vehicles, and personnel carriers: the 3AC "melted away" according to '' Forbes'', having little or no impact on the battlefield along with other irregular forces.

in a defence ministry meeting said that Russia planned to extend its Mykolayiv–Odesa front after the siege of Mariupol further west to include the breakaway region of Transnistria on the Ukrainian border with Moldova. The Ministry of Defence of Ukraine described this intention as

, saying that it contradicted previous Russian claims that it did not have territorial ambitions in Ukraine and that the statement was an admission that "the goal of the 'second phase' of the war is not victory over the mythical Nazis, but simply the occupation of eastern and southern Ukraine". Georgi Gotev, writing for Reuters on 22 April, noted that occupying Ukraine from Odesa to Transnistria would transform it into a

without any practical access to the Black Sea. On 24 April, Russia resumed its missile strikes on Odesa, destroying military facilities and causing two dozen civilian casualties. On 27 April, Ukrainian sources indicated that explosions had destroyed two Russian broadcast towers in Transnistria, primarily used to rebroadcast Russian television programming. At the end of April, Russia renewed missile attacks on runways in Odesa, destroying some of them. During the week of 10 May, Ukrainian troops began to take military action to dislodge Russian forces installing themselves on Snake Island in the Black Sea approximately from Odesa. On 30 June 2022, Russia announced that it had withdrawn troops from the island after objectives were completed. On 23 July, CNBC reported a Russian missile strike on Ukrainian port Odesa stating that the action was swiftly condemned by world leaders, a dramatic revelation amid a recently U.N. and Turkish-brokered deal that secured a sea corridor for grains and other foodstuff exports. On 31 July, CNN reported significant intensification of the rocket attacks and bombing of Mykolaiv by Russians also killing Ukrainian grain tycoon Oleksiy Vadaturskyi in the city during the bombing.

and Zaporizhzhia. On 10 April, Russian missiles destroyed the Dnipro International Airport. On 2 May the UN reportedly evacuated about 100 survivors from the siege at Mariupol with the cooperation of Russian troops, to the village of Bezimenne near Donetsk, from whence they were to move to Zaporizhzhia. On 28 June, Reuters reported that a Russian missile attack was launched upon the city of Kremenchuk north-west or Zaporizhzhia detonating in a public mall and causing at least 18 deaths while drawing condemnation from France's Emmanuel Macron, among other world leaders, who spoke of it as being a "war crime". 2022 July Dnipro missile strike killed four. On 7 July, it was reported that after the Russians captured the nuclear plant at Zaporizhzhia earlier in the invasion, they installed heavy artillery and mobile missile launchers between the separate reactor walls of the nuclear installation, using it as a shield against possible Ukrainian counterattack. A counterattack against the installed Russian artillery sites would not be possible without the risk of radiation fallout in case of near misses. On 19 August, Russia agreed to allow IAEA inspectors access to the Zaporizhzhia plant from Ukrainian-held territory, after a phone call between the President of France,

The next day, United States congressman Adam Kinzinger said that any radiation leak would kill people in NATO countries, which would be an automatic activation of Article 5. Shelling hit coal ash dumps at the neighbouring coal-fired power station on 23 August, and ash was on fire by 25 August. The 750 kV transmission line to the Dniprovska substation, which was the only one of the four 750 kV transmission lines that had not yet been damaged and cut by military action, passes over the ash dumps. At 12:12 p.m. on 25 August the line cut off due to the fire below, disconnecting the plant and its two operating reactors from the national grid for the first time since it started operating in 1985. In response, reactor 5's back-up generators and coolant pumps started up, and reactor 6 reduced generation. Incoming power was still available via the 330 kV line to the substation at the coal-fired station, so the diesel generators were not essential for cooling reactor cores and spent fuel pools. The 750 kV line and reactor 6 resumed operation at 12:29 p.m., but the line was cut by fire again two hours later. The line, but not the reactors, resumed operation again later that day. On 26 August, one reactor restarted in the afternoon and another in the evening, resuming electricity supplies to the grid. On 29 August 2022, an IAEA team led by Rafael Grossi went to investigate the plant. Lydie Evrard and

in the city of Kramatorsk took place on 8 April, reportedly killing at least 52 and injuring 87 to 300. On 11 April, Zelenskyy said that Ukraine expected a major new Russian offensive in the east. American officials said that Russia had withdrawn or been repulsed elsewhere in Ukraine, and therefore was preparing a retraction, resupply, and redeployment of infantry and tank divisions to the south-eastern Ukraine front. Military satellites photographed extensive Russian convoys of infantry and mechanised units deploying south from Kharkiv to Izium on 11 April, apparently part of the planned Russian redeployment of its north-eastern troops to the south-eastern front of the invasion. On 14 April, Ukrainian troops reportedly blew up a bridge between Kharkiv and Izium used by Russian forces to redeploy troops to Izium, impeding the Russian convoy. On 18 April, with Mariupol almost entirely overtaken by Russian forces, the Ukrainian government announced that the second phase of the reinforced invasion of the Donetsk, Luhansk and Kharkiv regions had intensified with expanded invasion forces occupying of the Donbas. On 5 May, David Axe writing for ''Forbes'' stated that the Ukrainian army had concentrated its 4th and 17th Tank Brigades and the 95th Air Assault Brigade around Izium for possible rearguard action against the deployed Russian troops in the area; Axe added that the other major concentration of Ukraine's forces around Kharkiv included the 92nd and 93rd Mechanized Brigades which could similarly be deployed for rearguard action against Russian troops around Kharkiv or link up with Ukrainian troops contemporaneously being deployed around Izium. On 13 May, BBC reported that Russian troops in Kharkiv were being retracted and redeployed to other fronts in Ukraine following the advances of Ukrainian troops into surrounding cities and Kharkiv itself, which included the destruction of strategic pontoon bridges built by Russian troops to cross over the Seversky Donets river and previously used for rapid tank deployment in the region. On 22 May, the BBC reported that after the fall of Mariupol, Russia had intensified offensives in Luhansk and Donetsk while concentrating missile attacks and intense artillery fire on Sievierodonetsk, the largest city under Ukrainian control in Luhansk province. On 23 May, Russian forces were reported entering the city of

, fully capturing the city by 26 May. Ukrainian forces were reported leaving Sviatohirsk. By 24 May, Russian forces captured the city of Svitlodarsk. On 30 May, Reuters reported that Russian troops had breached the outskirts of Sievierodonetsk. By 2 June, ''The Washington Post'' reported that Sievierodonetsk was on the brink of capitulation to Russian occupation with over 80 per cent of the city in the hands of Russian troops. On 3 June, Ukrainian forces reportedly began a counter-attack in Sievierodonetsk. By 4 June, Ukrainian government sources claimed 20% or more of the city had been recaptured. On 12 June it was reported that possibly as many as 800 Ukrainian civilians (as per Ukrainian estimates) and 300–400 soldiers (as per Russian sources) were besieged at the Azot chemical factory in Severodonetsk. With the Ukrainian defences of Severodonetsk faltering, Russian invasion troops began intensifying their attack upon the neighbouring city of Lysychansk as their next target city in the invasion. On 20 June it was reported that Russian troops continued to tighten their grip on Severodonetsk by capturing surrounding villages and hamlets surrounding the city, most recently the village of Metelkine. On 24 June, CNN reported that, amid continuing scorched-earth tactics being applied by advancing Russian troops, Ukraine's armed forces were ordered to evacuate the city; they'd leave several hundred civilians seeking refuge in the Azot chemical plant in Severodenetsk, which has been compared to the civilian refugees left at the Azovstal steel works in Mariupol during May. On 3 July, CBS announced that the Russian defense ministry claimed that the city of Lysychansk had been captured and occupied by Russian forces. On 4 July, ''The Guardian'' reported that after the fall of the Luhansk oblast, that Russian invasion troops would continue their invasion into the adjacent Donetsk Oblast to attack the cities of Sloviansk and

Fall of Mariupol

On 13 April, Russian forces intensified their attack on the Azovstal iron and steel works in Mariupol, and the Ukrainian defence forces that remained there. By 17 April, Russian forces had surrounded the factory. Ukrainian prime minister

said that the Ukrainian soldiers had vowed to ignore the renewed ultimatum to surrender and to fight to the last soul. On 20 April, Putin said that the siege of Mariupol could be considered tactically complete, since the 500 Ukrainian troops entrenched in bunkers within the Azovstal iron works and estimated 1,000 Ukrainian civilians were completely sealed off from any type of relief in their siege. After consecutive meetings with Putin and Zelenskyy, UN Secretary-General Guterres on 28 April said he would attempt to organise an emergency evacuation of survivors from Azovstal in accordance with assurances he had received from Putin on his visit to the Kremlin. On 30 April, Russian troops allowed civilians to leave under UN protection. By 3 May, after allowing approximately 100 Ukrainian civilians to depart from the Azovstal steel factory, Russian troops renewed non-stop bombardment of the steel factory. On 6 May, ''The Telegraph'' reported that Russia had used thermobaric bombs against the remaining Ukrainian soldiers, who had lost contact with the Kyiv government; in his last communications, Zelenskyy had authorised the commander of the besieged steel factory to surrender as necessary under the pressure of increased Russian attacks. On 7 May, the Associated Press reported that all civilians were evacuated from the Azovstal steel works at the end of the three-day ceasefire. After the last civilians evacuated from the Azovstal bunkers, nearly two thousand Ukrainian soldiers remained barricaded there, with 700 injured; they were able to communicate a plea for a military corridor to evacuate, as they expected summary execution if they surrendered to the Russians. Reports of dissent within the Ukrainian troops at Azovstal were reported by ''Ukrainskaya Pravda'' on 8 May indicating that the commander of the Ukrainian Marines assigned to defend the Azovstal bunkers made an unauthorised acquisition of tanks, munitions, and personnel, broke out from the position there and fled. The remaining soldiers spoke of a weakened defensive position in Azovstal as a result, which allowed progress to advancing Russian lines of attack. Ilia Somolienko, deputy commander of the remaining Ukrainian troops barricaded at Azovstal, said: "We are basically here dead men. Most of us know this and it's why we fight so fearlessly." On 16 May, the Ukrainian General staff announced that the Mariupol garrison had "fulfilled its combat mission" and that final evacuations from the Azovstal steel factory had begun. The military said that 264 service members were evacuated to Olenivka under Russian control, while 53 of them who were "seriously injured" had been taken to a hospital in Novoazovsk also controlled by Russian forces. Following the evacuation of Ukrainian personnel from Azovstal, Russian and DPR forces fully controlled all areas of Mariupol. The end of the battle also brought an end to the Siege of Mariupol. Russia press secretary Dmitry Peskov said Russian President

had guaranteed that the fighters who surrendered would be treated "in accordance with international standards" while Ukrainian President

said in an address that "the work of bringing the boys home continues, and this work needs delicacy — and time". Some prominent Russian lawmakers called on the government to deny prisoner exchanges for members of the Azov Regiment.

Third phase: Counteroffensives and annexations (6 Septemberpresent)

2022 Russian Invasion of Ukraine Phase 3 animated (cropped)

On 6 September 2022, Ukrainian forces launched a surprise counteroffensive in the Kharkiv region, beginning near Balakliia. By 12 September, an emboldened Kyiv launched a counteroffensive in the area surrounding Kharkiv with sufficient success for Russia to publicly admit to losing key positions in the area. ''The New York Times'' reported on 12 September that the success of the counteroffensive dented the image of a "Mighty Putin", and led to encouraging the government in Kyiv to seek more arms from the West to sustain its counteroffensive in Kharkiv and surrounding areas. On 21 September 2022, Vladimir Putin announced a partial mobilization. He also said that his country will use "all means" to "defend itself". Later that day, minister of defence Sergei Shoigu stated that 300,000 reservists would be called on a compulsory basis. Mykhailo Podolyak, the adviser to the president of Ukraine Volodymyr Zelenskyy, said that the decision was predictable, and was an attempt to justify "Russia's failures". British Foreign Office Minister Gillian Keegan called the situation an "escalation", while former Mongolian president

Since mid-October, Russia has carried out waves of strikes on Ukrainian electrical and water systems. On 15 November 2022, Russia fired 85 missiles at the Ukrainian Power Grid, causing major power outages in Kyiv and neighboring regions. A missile, initially reported to be Russian and later claimed to be "Russian-made", crossed into Poland, killing two people in

, which led to the top leaders of Poland holding an emergency meeting. The next day, US president Joe Biden stated that the missile that struck Polish territory was ‘unlikely’ to have been fired from Russia.

Annexations

In late September 2022, Russian-installed officials in Ukraine organized referendums on annexation of occupied territories of Ukraine, including the Donetsk People's Republic and the Luhansk People's Republic in Russian occupied Donetsk and Luhansk oblasts of Ukraine, as well as the Russian-appointed military administrations of Kherson Oblast and Zaporizhzhia Oblast. Denounced by Ukraine's government and its allies as sham elections, the official results showed overwhelming majorities in favor of annexation. On 30 September 2022, Vladimir Putin announced the annexation of Ukraine's Donetsk, Luhansk, Kherson and Zaporizhzhia regions in an address to both houses of the Russian parliament. Ukraine, the United States, the European Union and the United Nations all condemned the annexation.

Kherson counteroffensive

On 29 August, Zelenskyy advisedly vowed the start of a full-scale counteroffensive in the southeast. He first announced a counteroffensive to retake Russian-occupied territory in the south concentrating on the Kherson-Mykolaiv region, a claim that was corroborated by the Ukrainian parliament as well as

. At the start of the operation, the Ukrainian operational group "Kakhovka" and some Ukrainian officials claimed that their forces had broken through defensive lines manned by the 109th DPR Regiment and Russian paratroopers. The 109th DPR Regiment, which was a conscript unit that was known to serve on garrison duty in the Kherson area, was reported to have withdrawn from it. Ukrainian officials also claimed that they had hit and destroyed a large Russian base in the area amid a general increase of Ukrainian air and artillery bombardments of Russian positions. On 1 September, the Ukrainian army claimed to have captured Stanislav and Snihurivka, confirmed by local sources. On 4 September, Zelenskyy announced the liberation of two unnamed villages in Kherson Oblast and one in Donetsk Oblast. Ukrainian authorities released a photo showing the raising of the Ukrainian flag in Vysokopillia by Ukrainian forces. On 6 September, Ukraine started a second offensive in the Kharkiv area, where it achieved a rapid breakthrough. Meanwhile, Ukrainian attacks also continued along the southern frontline, though reports about territorial changes were largely unverifiable. On 12 September, Zelenskyy said that Ukrainian forces had retaken a total of from Russia, in both the south and the east. The BBC stated that it could not verify these claims. By 13 September, that Russian forces had withdrawn from Kyselivka, a settlement 15 km from Kherson. On the same day, the Russia-backed deputy head of the Kherson Region posted a video from the outskirts of the settlement in which he claimed that Ukrainian troops have not been able to enter it. The mayor of

reported that Russian forces were abandoning the city and were moving to Russian-held

. Ukraine also claimed to have retaken Oleksandrivka on 13 September. A local official claimed that Ukraine had retaken Kyselivka, but this had not been confirmed by the Ukrainian military or outside sources such as the ISW as of 14 September. In October, Ukrainian forces pushed further south towards the city of Kherson, taking control of of territory, with fighting extending to Dudchany. On 9 November, defence minister Shoigu ordered Russian forces to leave part of

, and move to the eastern bank of the Dnieper. On 11 November, Ukrainian troops entered Kherson, as Russia stated its withdrawal had been completed. This meant that Russian forces no longer had a foothold west of the Dnieper River (its right bank).

Kharkiv counteroffensive

Meanwhile, Ukrainian forces launched another surprise counteroffensive on 6 September in the Kharkiv region, beginning near Balakliia. By 7 September, Ukrainian forces had advanced some into Russian occupied territory and claimed to have recaptured approximately . Russian commentators said this was likely due to the relocation of Russian forces to Kherson in response to the Ukrainian offensive there. On 8 September, Ukrainian forces captured Balakliia and advanced to within of Kupiansk. Military analysts said Ukrainian forces appeared to be moving towards Kupiansk, a major railway hub, with the aim of cutting off the Russian forces at Izium from the north. On 9 September, the Russian occupation administration of Kharkiv Oblast announced it would "evacuate" the civilian populations of Izium, Kupiansk and

. The Institute for the Study of War said it believed Kupiansk would likely fall in the next 72 hours, while Russian reserve units were sent to the area by both road and helicopter. On the morning of 10 September, photos emerged claiming to depict Ukrainian troops raising the Ukrainian flag in the centre of Kupiansk, and the Institute for the Study of War said Ukrainian forces had captured approximately by effectively exploiting their breakthrough. Later in the day, ''Reuters'' reported that Russian positions in northeast Ukraine had "collapsed" in the face of the Ukrainian assault, with Russian forces forced to withdraw from their base at Izium after being cut off by the capture of Kupiansk.

The offensive continued pushing east and by 2 October Ukrainian Armed Forces had liberated another key city in the Second Battle of Lyman.

Dnipro–Zaporizhzhia front

On 3 September 2022, an IAEA delegation visited the nuclear power plant at Zaporizhzhia and on 6 September a report was published documenting damages and threats to the plant security caused by external shelling and presence of occupational troops in the plant. On 11 September, at 3:14 a.m., the sixth and final reactor was disconnected from the grid, "completely stopping" the plant. The statement from Energoatom said that "Preparations are underway for its cooling and transfer to a cold state".

On 31 July 2022, Russian Navy Day commemorations were cancelled after a drone attack reportedly wounded several people at the Russian Black Sea Fleet headquarters in Sevastopol. On 9 August 2022, there were large explosions reported at Saky Air Base in western Crimea. Satellite imagery showed that at least eight aircraft were damaged or destroyed. The cause of the explosions is unknown, but may have been long-range missiles, sabotage by special forces or an accident; Ukrainian commander-in-chief Valerii Zaluzhnyi claimed on 7 September that it had been a Ukrainian missile attack. The base is located near the town of Novofedorivka, which is popular with tourists. Queues to leave the area formed at the Crimean Bridge after the explosions. A week later there were explosions and a fire at an arms depot near Dzhankoi in northeastern Crimea, which Russia blamed on "sabotage". A railway line and power station were also damaged. According to the Russian regional head, Sergei Aksyonov, 2,000 people were evacuated from the area. On 18 August, explosions were reported at Belbek Air Base, north of Sevastopol. On the morning of 8 October, the Kerch Bridge, which links occupied Crimea with Russia, was hit by a large explosion which collapsed part of the roadway and caused damage to the railway line.

Missile attacks and aerial warfare

Aerial warfare began on the first day of the invasion. By September, the Ukrainian air force was still at 80% of its prewar strength and had shot down about 55 Russian warplanes. By late December, 173 Ukrainian aircraft and UAVs were confirmed to have been shot down, whereas Russia had lost 171 aircraft. With the the beginning of the invasion, dozens of missile attacks were recorded across both Eastern Ukraine and Western Ukraine. Dozens of missile strikes across Ukraine also reached as far west as Lviv. Starting in mid-October, Russian forces launched massive missile strikes against Ukrainian infrastructure, intending to knock out energy facilities throughout the country. By late November, hundreds of civilians had been killed and wounded by the attacks, and millions of civilians had been left without power due to rolling blackouts.

After the bombardment, a detachment of Russian soldiers landed and took control of Snake Island. Russia stated on 26 February that US drones supplied intelligence to the Ukrainian navy to help target Russian warships in the Black Sea, which the US denied. By 3 March, the Ukrainian frigate , the flagship of the Ukrainian navy, was scuttled in Mykolaiv to prevent its capture by Russian forces. On 14 March, the Russian source RT reported that the Russian Armed Forces had captured about a dozen Ukrainian ships in Berdiansk, including the .

On 1 June, Russian Foreign Minister Sergey Lavrov asserted that Ukraine's policy of mining its own harbours to impede Russia maritime aggression had contributed to the food export crisis, stating that: "If Kyiv solves the problem of demining ports, the Russian Navy will ensure the unimpeded passage of ships with grain to the Mediterranean Sea." On 30 June 2022, Russia announced that it had withdrawn troops from the island in a "gesture of goodwill". The withdrawal was later officially confirmed by Ukraine.

Nuclear threats

Four days into the invasion, President Putin placed Russia's nuclear forces on high alert, raising fears that Russia could use tactical nuclear weapons against Ukraine, or a wider escalation of the conflict could occur. During April, Putin and Russian foreign minister Sergei Lavrov made a number of threats alluding to the use of nuclear weapons against Ukraine and the countries supporting Ukraine. On 14 April, CIA director William Burns said that "potential desperation" in the face of defeat could encourage President Putin to use tactical nuclear weapons. In response to Russia's disregard of safety precautions during its occupation of the disabled former nuclear power plant at Chernobyl and its firing of missiles in the vicinity of the active nuclear power plant at Zaporizhzhia, on 26 April President Zelenskyy called for an international discussion on regulating Russia's use of nuclear resources, stating: "no one in the world can feel safe knowing how many nuclear facilities, nuclear weapons and related technologies the Russian state has... If Russia has forgotten what Chernobyl is, it means that global control over Russia's nuclear facilities, and nuclear technology is needed." In August, shelling around the Zaporizhzhia Nuclear Power Plant developed into a crisis, prompting an emergency inspection by the

. Ukraine has described the crisis as an act of nuclear terrorism by Russia. On 19 September, CNBC reported that Biden's response to Russian uncertainties about its lack of combat success in its invasion stating: "President Joe Biden warned of a 'consequential' response from the U.S. if Russian President Vladimir Putin were to use nuclear or other non-conventional weapons... Asked what he would say to Putin if he was considering such action, Biden replied, 'Don't. Don't. Don't.'" Following his statement made on 19 September, Biden appeared before the United Nations on 21 September and continued his criticism of Putin's nuclear , stating that Putin was "overt, reckless and irresponsible... A nuclear war cannot be won and must never be fought."

Ukrainian resistance

Ukrainian civilians resisted the Russian invasion, volunteered for territorial defence units, made Molotov cocktails, donated food, built barriers such as

, and helped to transport refugees. Responding to a call from Ukraine's transportation agency, Ukravtodor, civilians dismantled or altered road signs, constructed makeshift barriers, and blocked roadways. Social media reports showed spontaneous street protests against Russian forces in occupied settlements, often evolving into verbal altercations and physical standoffs with Russian troops. By the beginning of April, Ukrainian civilians began to organise as guerrillas, mostly in the wooded north and east of the country. The Ukrainian military announced plans to launch a large-scale guerrilla campaign to complement its conventional defence against the Russian invasion. People physically blocked Russian military vehicles, sometimes forcing them to retreat. The Russian soldiers' response to unarmed civilian resistance varied from reluctance to engage the protesters to firing into the air or directly into crowds. There have been mass detentions of Ukrainian protesters, and Ukrainian media reported forced disappearances, mock executions, hostage-taking, extrajudicial killing, and sexual violence perpetrated by the Russian military. To facilitate Ukrainian attacks, civilians reported Russian military positions via a Telegram chatbot and Diia, a Ukrainian government app previously used by citizens to upload official identity and medical documents. In response, Russian forces began destroying mobile phone network equipment, searching door-to-door for smartphones and computers, and in at least one case killing a civilian found with pictures of Russian tanks. As of 21 May, President Zelensky indicated that Ukraine had 700,000 servicemembers on active duty combating the Russian invasion. Throughout 2022, Ukraine withdrew soldiers and military equipment deployed to United Nations peacekeeping missions, such as MONUSCO in the Democratic Republic of the Congo, back to Ukraine.

Countries supplying aid to Ukraine during the 2022 Russian invasion

The Kiel Institute has tracked $84.2B from 40 countries in financial, humanitarian, and military aid to Ukraine from 24 January to 3 August 2022. NATO is coordinating and assisting member states in providing billions of dollars in military equipment and financial aid to Ukraine. The United States has provided the most military assistance, having provided $16.8B since February 2022. Many NATO allies, such as Germany and Sweden, have reversed past policies against providing offensive military aid in order to support Ukraine. The European Union for the first time in its history supplied lethal arms and has provided €2.5B to Ukraine. Between 2014 and 2021, the UK, US, EU, and NATO provided mostly non-lethal military aid to Ukraine. Lethal military support was initially limited. The US began to sell weapons including

. On 26 February, US Secretary of State Antony Blinken announced $350 million in lethal military assistance, including anti-armor and anti-aircraft systems. The next day the EU stated that it would purchase €450 million (US$502 million) in lethal assistance and an additional €50 million ($56 million) in non-lethal supplies for Ukraine, with Poland handling distribution. During the first week of the invasion, NATO member states supplied more than 17,000 anti-tank weapons to Ukraine; by mid-March, the number was estimated to be more than 20,000. In three tranches agreed in February, March and April 2022, the European Union committed to €1.5 billion to support the capabilities and resilience of the Ukrainian Armed Forces and the protection of the Ukrainian civilian population, under the purview of the European Peace Facility line. As of 11 April, Ukraine had been provided with approximately 25,000 anti-air and 60,000 anti-tank weapon systems by the US and its allies. The following day, Russia reportedly received anti-tank missiles and RPGs from Iran, supplied through undercover networks via Iraq. On 19 April 2022, Romania announced a planned reform to the government decree that regulates the export of military weapons and national defence products to provide these weapons not only to NATO allies but also to Ukraine. The Ministry of Defense developed the draft decree stating that the reason behind this decision was Russia's aggression against Ukraine. However, on 27 April Defense Minister Vasile Dincu said that his plan had been discontinued. On 26 April, the US convened a

Some analysts had said HIMARS could be a "game-changer" in the war. * Under Secretary of Defense for Policy Colin Kahl stated that the US would be able to send more systems as the fighting evolves. On 10 June, an official from the Ukrainian military said that they were using 5,000 to 6,000 artillery rounds a day and would then be using 155-calibre NATO standard shells because all their Soviet-era guns had been destroyed. The official said the Russians had transformed the war into an artillery duel focused on the southeast of the country. On 12 June, a Ukrainian Presidential advisor put on Twitter a list of weapons that Ukraine needed to achieve "heavy weapons parity". The top item was "1000 howitzers caliber 155 mm". Ukraine claimed it had enough 155 mm ammunition but lacked the artillery to use it. According to Oryxspioenkop only 250 howitzers have been promised or delivered. On 13 June, a

correspondent said that the Ukrainian supply of Soviet-era ammunition had been exhausted and all they had was a dwindling supply obtained from friendly ex-Soviet countries. In June 2022 Germany declassified its list of military aid to Ukraine. For the 16 US-supplied HIMARS systems in Ukraine (2 August 2022), the US was providing more munitions (additional HIMARS rocket pods in monthly installments, as well as more 155-mm howitzer shells) at a cost of $550 million for the 17th Presidential drawdown package. The 18th US presidential drawdown package was released (8 Aug 2022), a $1 billion package including additional HIMARS rocket pods, 75,000 rounds of 155mm artillery ammunition, 20 120mm mortar systems and 20,000 rounds of 120mm mortar ammunition, National Advanced Surface-to-Air Missile Systems (NASAMS), 1000 Javelins and hundreds of AT4 anti-tank weapons, 50 armored medical treatment vehicles, Claymore mines, C4 explosives, and medical supplies. The 19th US presidential drawdown package (19 Aug 2022) was a $775 million package, which included additional HIMARS rocket pods, 16 105mm howitzers with 36,000 artillery rounds (this supplements the UK's past contributions of 105mm howitzers), 1000 anti-armor Javelins, 2000 anti-armor rounds for the Swedish

The Vampire contract was not yet let as of November 2022, with delivery to Ukraine after mid-2023. The longer-term deliveries of materiel will include 6 additional NASAMS air defense units and their attendant rounds (for a total of 8 units); up to 245,000 155mm howitzer shells; up to 65,000 120mm mortar rounds; up to 24 counter-battery radars, and the attendant training, maintenance, and sustainment. By 24 August 2022 US aid since January 2021 exceeded $13.5 billion. By August 2022, the United Kingdom had provided military aid to the value of £2.3bn ($2.8bn). This included three M270 Multiple Launch Rocket Systems, some 5,000 NLAW anti-tank missiles, "hundreds" of Brimstone missiles, 120 armoured vehicles including Mastiff Protected Patrol Vehicles, and heavy-lift drones. Additionally, 10,000 Ukrainian soldiers were in an intensive 120-day infantry training course at four bases in Britain, delivered by a multi-national team of trainers. On 8 September 2022, US secretary of state Blinken announced $2 billion in aid to Ukraine and eighteen partners in the defence industrial base. In addition US secretary of defense Austin announced the 20th drawdown package —up to $675 million for Ukraine military aid at the Ukraine Defense Contact Group meeting in Germany, as well as discussion of initiatives for the respective industrial bases of the Defense Contact Group, in order to defend Ukraine's sovereign territory for the long haul. On 28 September William LaPlante, US under-secretary of defense for acquisition and sustainment ( USD (A&S)) met in Brussels with 40 counterparts in the Ukraine Defense Contact Group. On the agenda was the identification of industrial suppliers of replacement materiel such as gun barrels, ball bearings, steel casings, and microchips, without which the existing military aid will eventually cease to function due to heavy use on the battlefield. LaPlante later noted that a policy of "interoperability, but interchangeability, with multiple plants in multiple countries making identical items" will have a deterrent effect on the adversaries of those countries, as well as on the adversaries of Ukraine.

A proposal to administer US security assistance as part of EUCOM is under consideration at the Pentagon. This plan would systematise the services currently being provided to Ukraine on an '' ad hoc'' basis, and would provide a long-term vehicle for countering Russian plans under the provisions of the Lend-Lease act, and for coordinating Allied aid for Ukraine's defense with Ukrainian requests at a single point of contact in Wiesbaden, Germany. On 4 October 2022 the 22nd Presidential drawdown from US stocks to Ukraine, $625 million in security assistance, included a tailored package: 4 more

systems and their associated rockets; 16 more M777 155mm howitzers and 75,000 155mm rounds; 500 M982 Excalibur precision-guided 155mm rounds; 1,000 155mm rounds of remote anti-armor mine systems; 16 more 105mm M119 howitzers; 30,000 120 mm mortar rounds; 200 mine-resistant, ambush-protected vehicles ( MRAPs); 200,000 rounds of small arms ammunition; and Claymore mines. The package responds to current Ukrainian ammunition consumption rates during their latest offensives; more aid is forthcoming according to Laura Cooper, a US DoD deputy assistant secretary of defense. So far, the security assistance has totalled $16.8 billion to Ukraine. On 14 October 2022 the 23rd Presidential drawdown from US stocks provided Ukraine $725 million in security assistance, including additional rounds for High Mobility Artillery Rocket Systems (HIMARS); 23,000 155mm howitzer rounds; 500 precision-guided 155mm artillery rounds; 5,000 155mm rounds of Remote Anti-Armor Mine (RAAM) Systems; 5,000 anti-tank weapons; High-speed Anti-radiation missiles (HARMs); more than 200 High Mobility Multipurpose Wheeled Vehicles (HMMWVs); small arms and more than 2,000,000 rounds of small arms ammunition; and medical supplies.

The planned training cost would be nearly €107 million. ;Aid in construction of a missile defence system Missile defence of Ukraine was arriving piecemeal; in Brussels on 12 October 2022, US Army General Mark Milley suggested to the Ukraine Defense Contact Group that the allies of Ukraine "chip in to help Ukraine rebuild and sustain an integrated air and missile defense system" from the contributed air and missile defence system materiel. Specifically, Ukraine would need to link together and integrate their existing materiel and radars with " command and control and communication systems". On 28 October 2022 the Pentagon announced the 24th Presidential drawdown of materiel worth $275 million; the security assistance has totalled $18.5 billion to Ukraine since January 2021. The aid includes 500 Excalibur precision-guided 155mm artillery rounds, 2000 155mm remote anti-armor mine systems, more than 1,300 anti-armor weapons, more than 2.75 million rounds of small arms ammunition, more HIMARS rockets, 125 Humvees, and four satellite communications antennas for Ukraine's command and control systems, as well as training for operation of the NASAMS units. Two NASAMS units arrived in Ukraine on 7 November 2022. ;Security Assistance Group Ukraine (SAGU) By 21 July 2022, the EUCOM Control Center-Ukraine/International Donor Coordination Centre (ECCU/IDCC) a joint cell formed in March 2022 had trained 1,500 Ukrainian Armed Forces members on coalition-donated equipment. By 4 November 2022, the equipment shipments, and training measures of the Ukraine Contact Group had become repeatable enough to systematise in a Security Assistance Group Ukraine ( SAGU), based in Wiesbaden, Germany. On 4 November 2022 the Pentagon announced a $400 million USAI security assistance package to refurbish 45 T-72 tanks from the Czech Republic with "advanced optics, communications and armor packages"; in addition 1,100 Phoenix Ghost tactical unmanned aerial systems (UASs), and "40 armored riverine boats" are in the package. The combined additional aid amounts to 90 more T-72s by year-end 2022, plus 250 M1117 Armored Security Vehicles furnished for the first time, as well as the refurbished HAWK missiles from the Czech Republic, which will serve on the HAWK launchers from Spain. On 10 November, the $400 million aid announcement was clarified: 4 Stinger-based air defense AN/TWQ-1 Avengers, to counter the Iranian drones, were provided to Ukraine for the first time, as well as additional HIMARS rockets, 10,000 mortar rounds, thousands of 155mm howitzer rounds, 400 grenade launchers, 100 Humvees, 20 million rounds of small arms ammunition, and cold-weather gear. So far, the 20 HIMARS launchers drawn from US stocks are still in service; hundreds of T-72s have already been provided by Poland and other nations; the USAI security assistance has totalled $18.9 billion to Ukraine since January 2021. On 15 November 2022 the US White House Office of Management and Budget asked Congress for an additional $38 billion in fiscal year 2023 in aid for Ukraine. The supplemental funding request included $21.7 billion in security assistance, $14.5 billion in US State department sources and USAID sources to be provided to Ukraine's government, humanitarian relief, and global food security, as well as a $900 million request for the Department of Health and Human Services, to "provide standard assistance health care and support services to Ukrainian parolees"; in addition a $626 million Energy Department request would aid nuclear security at the power plant in Zaporizhzhia. In addition the US White House is requesting that Congress grant $7 billion in additional presidential drawdown authority from existing Defense department materiel. Were Congress to grant this fourth request, the total aid to Ukraine would be $104 billion in less than a year. On 17 November 2022, it was reported that Israel approved the transfer of weapons systems with Israeli parts, via NATO countries including the UK. These include advanced fire-control and electro-optic systems. It also agreed to buy strategic materials for the Ukrainian armed forces. On 23 November 2022 the Pentagon announced its 26th drawdown package of up to $400 million in aid.Stephen Lose

Foreign military involvement

Although NATO and the EU have publicly taken a strict policy of "no boots on the ground" in support against the Russian invasion of Ukraine, the United States has significantly increased the secret involvement of special operations military and CIA operatives in support of Ukrainian forces since the beginning of the invasion. In addition, Ukraine has actively sought volunteers from other countries. On 1 March, Ukraine temporarily lifted visa requirements for foreign volunteers who wished to join the fight against Russian forces. The move came after Zelenskyy created the International Legion of Territorial Defense of Ukraine and called on volunteers to "join the defence of Ukraine, Europe and the world". The U.S. also assisted Ukraine with military planning, including war-gaming counteroffensive options. Ukraine's foreign minister Dmytro Kuleba stated that as of 6 March, approximately 20,000 foreign nationals from 52 countries have volunteered to fight. Most of these volunteers joined the newly created International Legion of Territorial Defense of Ukraine. On 9 June, the

sentenced three foreign volunteers to death. Two of them were British citizens and one was a Moroccan national. The foreign prisoners were later released. On 3 March, Russian Defence Ministry spokesman Igor Konashenkov warned that mercenaries are not entitled to protection under the Geneva Conventions, and captured foreign fighters would not be considered prisoners of war, but prosecuted as criminals. Shortly thereafter, however, on 11 March, Moscow announced that 16,000 volunteers from the Middle East were ready to join other pro-Russian foreign fighters alongside the Donbas separatists. A video uploaded online showed armed Central African paramilitaries preparing to fight in Ukraine with Russian troops. On 21 October, a White House press release stated that Iranian troops were in Crimea assisting Russia in launching drone attacks against civilians and civilian infrastructure. On 24 November Ukrainian officials said the military had killed ten Iranians and would target any further Iranian military presence in Ukraine.

Foreign sanctions and ramifications

Western countries and others imposed limited sanctions on Russia when it recognised Donbas as an independent nation. When the attack began, many other countries applied sanctions intended to cripple the Russian economy. The sanctions targeted individuals, banks, businesses, monetary exchanges, bank transfers, exports, and imports. The sanctions cut major Russian banks from SWIFT, the global messaging network for international payments, but left some limited accessibility to ensure the continued ability to pay for gas shipments. Sanctions also included asset freezes on the

On 24 March, Joe Biden's administration issued an executive order that barred the sale of Russian gold reserves by US citizens; other G7 leaders took similar action. Gold has been one of Russia's major avenues to protect its economy from the impact of the sanctions imposed since the 2014 annexation of Crimea.

Foreign condemnation and protest

The invasion received widespread international condemnation and protests occurred around the world. On 2 March, the United Nations General Assembly passed UNGA resolution ES-11/1 condemning the invasion and demanding a full withdrawal of Russian forces. The International Court of Justice ordered Russia to suspend military operations, and the

expelled Russia. Many countries imposed sanctions on Russia, which have affected the economies of Russia and the world and provided humanitarian and military aid to Ukraine. The International Criminal Court opened an investigation into

in Ukraine since 2013, as well as war crimes in the 2022 invasion.

and video footage of military actions. Both Russian and Ukrainian sources are widely considered to inflate casualty numbers in opposing forces, while downplaying their own losses for the sake of morale. Russian news outlets have largely stopped reporting the Russian death toll. Russia and Ukraine admitted to suffering "significant" and "considerable" losses, respectively. BBC News reported in April 2022 that Ukrainian claims of Russian fatalities included the injured as well.

reported that more than 90,000 Russian soldiers had been killed, seriously wounded or gone missing in Ukraine, citing sources close to the Kremlin. The Office of the United Nations High Commissioner for Human Rights (OHCHR) considers the number of civilian casualties to be considerably higher than the figure the United Nations has been able to certify. On 16 June, the Ukrainian Minister of Defense told CNN that he believed tens of thousands of Ukrainians had died, adding that he hoped that the true death toll was below 100,000. In the destroyed city of Mariupol alone, Ukrainian officials believe at least 25,000 have been killed, but investigations of morgue records indicate many more, while still more bodies remain uncollected.

. A report by '' The Independent'' on 9 June cited an intelligence report estimating that more than 5,600 Ukrainian soldiers had been captured, while the number of Russian servicemen being held as prisoners had fallen to 550, from 900 in April, following several prisoner exchanges. In contrast, '' Ukrayinska Pravda'' claimed 1,000 Russian soldiers were being held as prisoners as of 20 June. The first large prisoner exchange took place on 24 March, when 10 Russian and 10 Ukrainian soldiers, as well as 11 Russian and 19 Ukrainian civilian sailors, were exchanged. On 1 April 86 Ukrainian servicemen were exchanged for an unknown number of Russian troops.

was published which reported the identification of some 21 filtration camps in and around Russian-controlled Donetsk oblast, run by Russian and Russian allied forces and used for Ukrainian "civilians, POWs, and other personnel". These camps were allegedly used for four main purposes: as registration points; as camps and other holding facilities for those awaiting registration; as interrogation centers; and as "correctional colonies" (i.e., prisons). At Olenivka prison, one of the identified camps, the disturbed earth seen in imagery was said by researchers to be consistent with graves. Kaveh Khoshnood, a professor at the Yale School of Public Health, said: "Incommunicado detention of civilians is more than a violation of international humanitarian law — it represents a threat to the public health of those currently in the custody of Russia and its proxies. The conditions of confinement documented in this report allegedly include insufficient sanitation, shortages of food and water, cramped conditions, and reported acts consistent with torture."

Humanitarian impact

The humanitarian impact of the invasion has been extensive and has included negative impacts on international food supplies and the

. The invasion has also had a negative impact upon the cultural heritage of Ukraine, with over 500 Ukrainian cultural heritage sites, including cultural centers, theatres, museums, and churches, having been impacted by "Russian aggression", and Ukraine's Minister of Culture calling it cultural genocide. The deliberate destruction and looting of Ukrainian cultural heritage sites in this way is considered a war crime.

Refugee crisis

02022 1199 Refugees from Ukraine in Kraków

The war caused the largest refugee and humanitarian crisis within Europe since the Yugoslav Wars in the 1990s; the UN described it as the fastest-growing such crisis since World War II. As Russia built up military forces along the Ukrainian border, many neighbouring governments and aid organisations prepared for a mass displacement event in the weeks before the invasion. In December 2021, the Ukrainian defence minister estimated that an invasion could force three to five million people to flee their homes. In the first week of the invasion, the UN reported over a million refugees had fled Ukraine; this subsequently rose to over 7,405,590 by 24 September, a reduction from over eight million due to some refugees' return. On 20 May, NPR reported that, following a significant influx of foreign military equipment into Ukraine, a significant number of refugees are seeking to return to regions of Ukraine which are relatively isolated from the invasion front in south-eastern Ukraine. However, by 3 May, another 8 million people were displaced inside Ukraine. Most refugees were women, children, the elderly, or people with disabilities. Most male Ukrainian nationals aged 18 to 60 were denied exit from Ukraine as part of mandatory conscription, unless they were responsible for the financial support of three or more children, single fathers, or were the parent/guardian of children with disabilities. Many Ukrainian men, including teenagers, in any case opted to remain in Ukraine to join the resistance. Regarding destinations, according to the UN High Commission for Refugees, as of 13 May, there were 3,315,711 refugees in Poland, 901,696 in Romania, 594,664 in Hungary, 461,742 in Moldova, 415,402 in Slovakia, and 27,308 in Belarus, while Russia reported it had received over 800,104 refugees. As of 23 March, over 300,000 refugees had arrived in the Czech Republic. Turkey has been another significant destination, registering more than 58,000 Ukrainian refugees as of 22 March, and more than 58,000 as of 25 April. The EU invoked the

Britain has accepted 146,379 refugees, as well as extending the ability to remain in the UK for 3 years with broadly similar entitlements as the EU, three years residency and access to state welfare and services.

In April, Ukraine's National Security and Defence Council secretary Oleksiy Danilov said Russia planned to build "concentration camps" for Ukrainians in western Siberia, and that it likely planned to force prisoners to build new cities in Siberia. A second refugee crisis created by the invasion and by the Russian government's suppression of human rights has been the flight of more than 300,000 Russian political refugees and economic migrants, the largest exodus from Russia since the

of 1917, to countries such as the

Fears arose in Russia over the effect of this flight of talent on economic development. Some Russian refugees sought to oppose Putin and help Ukraine from outside their country, and some faced discrimination for being Russian. There has also been an exodus of millionaires. On 6 May, '' The Moscow Times'', citing data from the FSB, reported that almost four million Russians had left the country, although this figure included travellers for business or tourism. Russia's partial mobilization of 300,000 men in September prompted an initial 200,000 more Russians to flee the country, rising to 400,000 by early October, double the number of those conscripted. , the

has likely resulted in tens of thousands of deaths on both sides and has caused Europe's largest refugee crisis since

, with an estimated 8 million people being displaced within the country by late May as well as 7.6 million Ukrainians fleeing the country as of 3 October 2022.

Reactions

United Nations General Assembly resolution ES-11 L

The invasion received widespread international condemnation from governments and intergovernmental organisations, with political reactions including new sanctions imposed on Russia, which triggered widespread economic effects on the Russian and world economies. The European Union and other Western governments financed and delivered humanitarian and military aid to Ukraine. The bloc also implemented various economic sanctions, including a ban on Russian aircraft using EU airspace, a SWIFT ban on certain Russian banks, and a ban on certain Russian media outlets. Reactions to the invasion have varied considerably across a broad spectrum of concerns including public response, media responses, peace efforts, and the examination of the legal implications of the invasion. The invasion received widespread public condemnation internationally, while in some countries, certain sectors expressed sympathy or outright support for Russia due in part to distrust of US foreign policy. Protests and demonstrations were held worldwide, including some in Russia and parts of Ukraine occupied by Russia. Calls for a boycott of Russian goods spread on social media platforms, while hackers attacked Russian websites, particularly those operated by the Russian government. Anti-Russian sentiment against Russians living abroad surged after the invasion.

Peace efforts

Peace negotiations between Russia and Ukraine took place on 28 February, 3 March, and 7 March 2022, in an undisclosed location in the Gomel Region on the Belarus–Ukraine border, with further talks held on 10 March in Turkey prior to a fourth round of negotiations which began on 14 March. The Ukrainian foreign minister Dmytro Kuleba stated on 13 July that peace talks are frozen for the time being. On 19 July, former Russian President and current Deputy head of the Russian Security Council,

, said: “Russia will achieve all its goals. There will be peace – on our terms.”
