Northern Syria Buffer Zone

The Northern Syria Buffer Zone (also known as the Safe Zone, Peace Corridor, or Security Mechanism) was a temporary Syrian Civil War demilitarized zone (DMZ) established on the Syrian side of the Syria–Turkey border in August 2019 to maintain security along the border and to dissuade a prospective Turkish invasion of the self-proclaimed Autonomous Administration of North and East Syria. The DMZ was administered by the Kurdish-led Syrian Democratic Forces (SDF) and their military councils and enforced by United States Armed Forces and Turkish Armed Forces personnel.

The buffer zone collapsed in early October 2019, before it was fully implemented, when Turkey dismissed the agreement on 1 October and the United States abandoned the effort on 6 October after U.S. President Donald Trump ordered the withdrawal of U.S. forces from northern Syria, allowing for Turkish President Recep Tayyip Erdoğan's planned ground incursion into the region. The subsequent Turkish offensive on 9 October rendered the buffer zone fully obsolete.

The failed Turkish-U.S. arrangement was replaced on 22 October 2019 with the separate Second Northern Syria Buffer Zone, negotiated between Russia, Turkey and the Syrian government.

Background

The Syrian Democratic Forces are an armed participant in the Syrian Civil War and serve as the armed forces of the Autonomous Administration of North and East Syria. The SDF is composed of numerous groups, most prominent among them being the YPG and YPJ and their political branch, the PYD, which Turkey considers a branch of the Kurdistan Workers' Party (PKK), an organization which Turkey considers a terrorist group and with which it has engaged in armed conflict since the breakdown of peace negotiations in 2015. For this reason, Turkey views the entire SDF as nothing more than an extension of the PKK. This has led Turkey to intervene twice against the group, first by invading Northern Syria to prevent the linking of SDF-held areas and later by starting a full-scale attack against the SDF in Afrin. As a result of the Turkish operations, Turkey has established an occupation zone in northern Syria, which was made the target of an SDF insurgency. Turkish President Recep Tayyip Erdoğan has frequently expressed a desire to forcefully remove the SDF from the Syrian-Turkish border.

On the other hand, the SDF became one of the United States' main Syrian partners in the military intervention against ISIL, leading to U.S. troops being stationed along SDF-held territories, thus preventing a Turkish invasion. At the same time, US President Donald Trump has expressed his intention to disengage from the Syrian Civil War, initially ordering all US personnel in Syria to be withdrawn, before later deciding to leave a small contingent, at the behest of his military advisors. Nonetheless, the US is keen on maintaining good relations with Turkey, which had by that point already been strained by the refusal of the US to extradite Turkish dissident Fethullah Gülen (whom Turkey accuses of masterminding the 2016 Turkish coup d'état attempt) and the Turkish purchase of S-400 missile systems from Russia, as Turkey is considered NATO's key member in the Middle East.

The US and Turkey had previously clashed diplomatically over the issue of the SDF-held city of Manbij, with Turkey wanting to purge the city of the YPG units stationed there. The result was a 'Manbij Roadmap' being agreed to by Turkey and the US, which would eventually entail a YPG withdrawal from the city. The roadmap, however, was never implemented and the YPG never withdrew. Turkey accused the US of dragging its feet and sabotaging the implementation of the roadmap, vowing to never enter into a similar deal in the future.

Relations between Turkey and the SDF became increasingly hostile in mid 2019, with the SDF joining forces with the Syrian Government to repel a Turkish-opposition military operation near Tell Rifaat.

Negotiation process

Preliminary negotiations and initial failure

During summer of 2019, the Turkish president announced that Turkey could "no longer wait" and would not tolerate continued SDF presence on the Turkish-Syrian border. He stated that if the US did not agree to a deal that would remove the SDF from those areas, Turkey would unilaterally launch a full-scale invasion against SDF-held territories east of the Euphrates river, establishing a Turkish-occupied "security zone" along the border - something that US leadership viewed as "unacceptable". With the Turkish army massing along the border, the Trump Administration decided to enter into negotiations with Turkey over establishing a "safe zone", which would fundamentally address the SDF presence in Northern Syria. The two sides initially failed to make any headway, with the US initially offering a -deep zone under joint US-Turkish control, while Turkey demanded a -deep zone under sole Turkish control.

Deal reached

On 7 August 2019, Turkey said it reached a framework deal with the United States, that would prevent a unilateral Turkish invasion of northern Syria. The initial first steps reportedly included the creation of a 'joint operations centre', which would coordinate the establishment of a "peace corridor" along the Syrian side of the Syrian-Turkish border, while still leaving details about the size and scope of the "peace corridor" undefined and ambiguous.

Terms of the agreement

In mid August 2019, the head of the Syrian Democratic Forces revealed that the two sides had agreed on the specifics of the safe zone deal. They were listed as follows:

* A buffer zone (also referred to as "safe zone" or "peace corridor" by some parties) would be established in the areas between the Tigris and Euphrates rivers (notably excluding the Manbij area) in Northern Syria, totaling in about 115 km of the border between the two countries.
* The zone would be deep in most areas, while in a few limited areas would be expanded to deep. The expanded part of the zone would be located between the towns Serêkanî and Tell Abyad. The 14 km portion of the zone may be extended by in the last stage of the implementation of the deal, reaching at its deepest point and being designated as a "security belt". Within the "security belt" regular SDF (including YPG and YPJ) units would be allowed to remain in their positions, but would have to withdraw all heavy weapons. No hostile actions or acts of aggression would be permitted within the buffer zone.
* YPG and YPJ forces would withdraw from the 5-9-14 km area of the buffer zone entirely, leaving the areas they withdraw from under the military control of the SDF military councils and the civil control of the Autonomous Administration of North and East Syria (the latter of which represents a confirmation of the status quo).
* Turkish reconnaissance aircraft would be allowed to monitor the zone, but Turkish warplanes would not be allowed to enter and no airstrikes would take place.
* The SDF would dismantle the border fortifications it has constructed along the Syrian-Turkish border.
* The US and Turkey would conduct joint military patrols along the buffer zone, but would not occupy territory. Separate Turkish patrols would not be permitted.
* The joint US-Turkish operations center would oversee the implementation of the deal and coordinate actions between the two parties.
* Some of the Syrian refugees currently housed in Turkey would start to be relocated to the areas within the zone.
*Turkey would refrain from any incursions into Northern Syria.
*Turkey would not establish any observation posts in Northern Syria, as it had done in Idlib. All observation posts would have to be built on the territory of the Republic of Turkey.

The SDF later clarified that the majority of the zone would include rural areas and military positions, but not cities and towns.

Implementation timeline

On 14 August 2019, Turkish observation drones began surveillance flights over the buffer zone.

On 22 August, the SDF began dismantling border fortifications along the Syrian-Turkish border under U.S. supervision.

On 24 August, Turkish defense minister Hulusi Akar reported that the U.S.-Turkish combined joint operations center (CJOC) was fully operational, adding that joint helicopter flights would begin that same day.

*The first joint U.S.-Turkish helicopter flight took place, with two generals, one from the U.S. Army and one from the Turkish army, flying on the same helicopter.

On 26 August, Turkish president Recep Tayyip Erdoğan stated that joint U.S.-Turkish patrols within the zone would begin "soon".

Planned SDF withdrawal begins

On 27 August, the first stage of the planned Kurdish withdrawal came into effect, with YPG units leaving their positions and withdrawing along with their weapons from Tell Abyad and Ras al-Ayn.

On 31 August, Turkish president Erdoğan threatened that Turkey would "implement its own plans" if Turkish soldiers are not allowed to control the buffer zone in Northern Syria within two or three weeks.

On 4 September, the SDF's Ras al-Ayn military council (composed of local fighters loyal to the SDF) began joint patrols with U.S. personnel around the town, following the withdrawal of regular SDF units from the area a week prior.
*Turkish president Erdogan described the buffer zone as "nothing more than a name". Despite Erdogan's statement, his spokesman stated that Turkey had already completed its preparations for the implementation of the "U.S.-Turkish joint operational plan".
*An SDF executive council co-chair stated that the buffer zone had gone off to a "good start," but insisted that Turkey must withdraw its troops from the border before "calm could prevail".

On 5 September, U.S. and Turkish helicopters conducted a third round of joint aerial reconnaissance patrols within the buffer zone.
*The Turkish president expressed his desire to resettle one million refugees (out of the 3.6 million residing in Turkey at that point) within the buffer zone. He accused the international community, namely the European Union, of not providing help with the refugee burden. He threatened to "open the gates", implying to let all of the refugees freely emigrate, if Turkey did not receive support for its plans in the buffer zone. He then demanded that joint U.S.-Turkish (ground) patrols within the zone begin by the last week of September.

On 6 September, Turkish defense minister Hulusi Akar announced that joint U.S.-Turkish ground patrols within the zone were due to begin on Sunday, 8 September.

Joint ground patrols begin

On 8 September, Turkish and United States Armed Forces personnel conducted their first joint ground patrol starting from the perimeter of Tell Abyad, close to the Turkish town of Akçakale. Six Turkish armored vehicles were involved in the patrol, along with several American armored vehicles, with the U.S. vehicles leading the way. The patrol headed to a Kurdish-controlled base to inspect it and to ensure that trenches and sand berms had been removed.
*The Syrian government vehemently condemned the initiation of joint patrols, stating that it viewed them as representing a flagrant violation of the country's national sovereignty and territorial integrity.
*The Turkish President expressed dissatisfaction with the buffer zone, accusing the United States of creating the buffer zone for the benefit of the YPG, instead of Turkey.

On 10 September, Turkish Foreign Minister Mevlüt Çavuşoğlu accused the United States of "stalling" the implementation of the zone and reasserted the threat that Turkey would unilaterally invade Northern Syria, if it deemed it necessary. He further demanded that the safe zone be expanded to 32 km, rather than the 5-9-14 model being implemented at that point by the U.S. and SDF.

On 12 September, the U.S. military was reported as considering the proposition of sending about 150 additional troops to Northern Syria in an attempt to "reduce tensions" between the SDF and Turkey. A Pentagon spokesman however stated that the U.S. "posture" in Syria would remain "unchanged".

On 18 September, Turkish president Erdogan stated Turkey was seeking to settle 2 to 3 million refugees within the border zone (up from one million from his 5 September statement). He reiterated the repeated Turkish threat to "implement urkey'sown plans" if he deemed that "no results adcome" from the deal in two weeks.

On 19 September, the U.S. military was reported to have continued arming YPG forces, despite repeated Turkish objections. The United States Department of Defense confirmed that it was continuing to supply "tailored" arms and vehicles to the Syrian Democratic Forces in general, stating that it was providing monthly reports to Turkey as to what arms and vehicles were sent to the group.

On 24 September, U.S. and Turkish troops conducted their second joint ground patrol within the buffer zone.

* Two Turkish Air Force F-16 jets were allowed to peacefully fly over the buffer zone area within the framework of the U.S.-led Operation Inherent Resolve.
* Turkish president Erdogan spoke before the United Nations General Assembly, stating that 3 million Syrian refugees could be resettled within the buffer zone, if it is extended all the way to Raqqa and the Syrian Government-held city of Deir ez-Zor. He also held up a map, which depicted a deep "safety corridor" in Northern Syria - reiterating the Turkish demand for an immediate extension of the buffer zone up to 30 km.
** The Syrian Democratic Forces denounced the Turkish President's statement, considering his proposed relocation plan for 3 million refugees as a form of demographic war and 'ethnic cleansing'.

Turkey dismisses buffer zone, threatens invasion

On 1 October, the Turkish-imposed deadline for the fulfillment of Turkish demands expired without satisfaction, casting uncertainty on the future of the Buffer Zone and leaving the region once more under threat of a Turkish incursion.

On 5 October, the Turkish President warned that a full-scale Turkish invasion of Northern Syria could start that same or following day, after defining the joint U.S.-Turkish ground and air patrols as "a fairy tale". He further stated that the Turkish military had already prepared for the attack and had received plans for the invasion.

* Rojava officials warned that any such attack could risk the re-emergence of ISIL, as SDF units would have to leave their garrisons in the recently secured former ISIL strongholds in order to face the invasion. At the same time, SDF officials warned that they would "not hesitate to turn any unprovoked attack by Turkey into an all-out war on the entire border and defend our people".
* United States Secretary of Defense Mark Esper gave an ambiguous statement on the Turkish threat, stating that the United States was "working to make the security mechanism functional".
* U.S.-led coalition jets intensively overflew the Syria-Turkish border, while SDF units were reported to have started constructing new trenches and fortifications south of the border in anticipation of an attack after having previously demolished its own fortifications along the border as part of the Buffer Zone deal. Meanwhile, the SDF military councils along the entire border were placed on alert and began preparing to resist Turkish forces.

U.S. forces withdraw, SDF pledges to fight

On 7 October, a White House Office press statement noted that Turkey would be "moving forward with its long-planned operation into northern Syria" and declared that while U.S. forces would not support the operation, they would withdraw from the area, essentially allowing it to take place. The statement reportedly suggested that U.S. President Donald Trump approved of the Turkish offensive after Turkish President Erdogan assured him that Turkey would take over the detention of ISIL prisoners held in SDF captivity. Trump's sudden approval of a Turkish incursion was seen as a reversal of the objectives of the Buffer Zone agreement and was received controversially within the United States. Spokesmen of the SDF said the U.S. move was a "stab in the back" and asserted that the SDF would "defend north-east Syria at all costs".

*Following the announcement of his approval of a Turkish operation, Trump tweeted a threat to Erdogan in which he stated that if Turkey took any action that he, in what he considered to be his "great and unmatched wisdom", deemed "off limits", he would "totally destroy and obliterate" the Turkish economy.
*U.S. Senator Lindsey Graham stated he would "introduce bipartisan sanctions against Turkey if they invade Syria". Graham said he would also "call for their suspension from NATO if they attack Kurdish forces who assisted the US in the destruction of the ISIS Caliphate".
*The SDF sent a large number of reinforcements from Raqqa and northern Deir ez-Zor toward the Syrian-Turkish border, particularly around the areas of Ras al-Ayn and Tell Abyad.
*Several thousand residents of the SDF-held city of Kobanî came out in a demonstration against Turkish threats.

On 8 October, SDF officials expressed their intentions to negotiate with Syrian President Bashar al-Assad for a deal that could see the entry of Syrian Army units into SDF-held territories, which they hope would forestall the planned Turkish invasion. Syria's Foreign Minister urged Kurdish forces to hand over several areas controlled by them to the Syrian Government, stating that should they refuse to do so, they would be faced with "abyss" in the face of Turkey. Masoud Barzani, senior politician in Iraqi Kurdistan Regional Government, urged Russia to intervene in the crisis in order to prevent "further suffering and pain of the Kurdish people in Syria".

End of demilitarization and beginning of Turkish offensive

On 9 October, Turkish President Erdogan announced that the offensive against the SDF, Operation Peace Spring, had begun.

* The Syrian Government strongly condemned the Turkish operation, accusing Turkey of "disgracefully" violating international law, as well as Syria's territorial integrity.
* The Syrian Democratic Forces urged the international community to implement a no-fly zone over Northern Syria, in order to prevent "an imminent humanitarian crisis".

Analysis

The Kurdish Rudaw Media Network asserted that Turkey does not have a pressing "security concern" for a buffer zone at all, noting that Turkey had managed to successfully prevent any border crossings during the Siege of Kobanî without the need for a buffer zone.

The Turkish Ahval agency reported that joint US-Turkish patrols suggested that the United States was "submitting" to Turkish demands and thus providing Turkey an 'entrée' into even more demands.

The Central Asia-Caucasus Institute's Turkey Analyst publication reported that Turkish authorities may view the buffer zone as a way to "move beyond Kobanî" and restart the by that point highly troubled US- Turkey relations, while giving political leverage to US President Donald Trump to continue delaying the implementation of US congress-mandated sanctions against Turkey, which were voted in due to the Turkish purchase of S-400 missile systems from Russia.

The conservative US Washington Examiner described the establishment of the buffer zone as "appeasement", which it dubbed "a terrible idea". The publication described Turkish intelligence as "deeply flawed and politicised", claimed that members of Turkish President Erdogan's family and even Erdogan himself might have "supported" both ISIL and Al-Qaeda and asserted that Turkey's previous incursion into Northern Syria had ended in "anti-Kurdish ethnic cleansing".

The Israeli ''Jerusalem Post'' newspaper described the establishment of the buffer zone due to Turkish threats as a "rewriting of international law", which implicitly recognized a "right to invade" and would have great implications for other world conflicts by allowing militarily powerful nations to unilaterally assert themselves over weaker ones.

Russian-Turkish buffer zone

On 22 October, the Turkish and Russian presidents met and reached a deal aimed at concluding the Turkish offensive, based in part on the first buffer zone deal, but with significant changes and excluding the United States.

Reactions

National

* — The Syrian Government strongly condemned and categorically rejected the deal, dubbing it a "blatant attack" on the nation's national sovereignty, as well as a violation of international law.
* — Turkish foreign minister Mevlüt Çavuşoğlu warned that Turkey would not allow the plans for the implementation of the buffer zone to "stall" and cautioned that Turkey would not tolerate a repetition of the unenforced Manbij roadmap. Cavusoglu further pleged to clear the buffer zone of "YPG terrorists". Turkish President Recep Tayyip Erdoğan expressed dissatisfaction with the size, scope and implementation timeline of the deal numerous times and has threatened to void the agreement, as well as allow free refugee migration to Europe, if the deal's terms are not altered and interpreted more in line with Turkey's vision for the zone.
* — The US embassy in Turkey released a statement, in which it noted that US and Turkish military delegations had met and agreed to work together to address Turkey's 'security concerns'.
* - Russia warned of what it deemed were efforts to divide northeastern Syria and added that any legitimate agreement would require the approval of the Syrian Government. Russia urged dialogue between the Syrian Government and Rojava as a means to prevent the partition of Syria. However, several weeks later, during a visit by Turkish President Recep Tayyip Erdoğan in Moscow, Russian President Vladimir Putin expressed his support for a buffer zone in principle, stating that Turkey had been shouldering a "huge refugee load" and had "legitimate concerns" over the security of its southern borders. Russian Foreign Minister Sergey Lavrov commented that Russia "always supports" de-escalation agreements, but insisted that all such agreements "respect Syria's sovereignty and territorial integrity as well as the rights of the Arab tribes, traditionally living around the Euphrates."
* - Iran condemned the agreement, considering it a "provocative and worrying step", which it deemed to violate the principles of international law and the Charter of the United Nations.
* - Shortly before joint US-Turkish ground patrols within the zone were due to begin, Denmark announced that it would be sending Danish army troops and medical personnel to SDF-held areas in Northern Syria, in what the Danish Government dubbed a move assist SDF and 'residual' U.S. forces in their fight against ISIL. The United States Department of Defense welcomed this announcement.

Non-state groups and organizations

* Syrian Democratic Forces — The SDF announced support for the deal, stating that they were ready to support its implementation and would "strike to ensure the success of efforts towards implementing the understanding ... with the Turkish state". At the same time, the co-chair of the foreign relations department at the Syrian Democratic Council has stated that the SDF would not tolerate any advance of Turkish troops, nor of their allied armed groups.
* - The Syrian opposition, of which Turkey is one of the largest backers, supported the Turkish position by demanding that the safe zone be expanded to between . The opposition Syrian Interim Government aspired to one day control the zone, stating that they had three files of 120 pages each, which documented a plan to govern the zone, should they somehow come to occupy it at some point in the future.
