Background

On 29 November 1947, the United Nations General Assembly adopted
Resolution 181 The United Nations Partition Plan for Palestine was a proposal by the United Nations, which recommended a partition of Mandatory Palestine at the end of the British Mandate. On 29 November 1947, the UN General Assembly adopted the Plan as Re ...
on "the future constitution and government of Palestine" setting forth a "Plan of Partition with Economic Union". The result of the vote was 33 in favour, 13 against and 10 abstentions. The report consisted of four parts: future constitution and government of Palestine; boundaries; city of Jerusalem; and capitulations. It called for the creation of Arab and Jewish states no later than 1 October 1948, with Jerusalem as ''
corpus separatum ''Corpus separatum'' is a Latin term referring to a city or region which is given a special legal and political status different from its environment, but which falls short of being sovereign, or an independent city state. The term may refer to: * ...
'' under an international regime to be administered by the U.N. with the Trusteeship Council being the designated body in this regard. The plan also included steps to be taken prior to independence, including the issues of citizenship, transit, economic union between the two states, access to holy places and religious and minority rights. Resolution 181 (II) also established the United Nations Palestine Commission to carry out the plan. The Trusteeship Council was to administer Palestine for ten years. As the civil war in Palestine began to escalate the Security Council voted on and adopted Resolution 42 (1948) of 5 March 1948, appealing to all governments and peoples, particularly in and around Palestine, to take all possible action to prevent or reduce such disorders as were occurring in Palestine. The Trusteeship Council decided on 10 March 1948 in resolution 32 (II) "that the statute on Jerusalem was in satisfactory form and agrees that the question of its formal approval, together with the appointment of a governor of the city, shall be taken up at a subsequent meeting to be held not later than one week before 29 April 1948", the deadline given to the council by the assembly. On 21 April 1948, the Trusteeship Council transmitted the Resolution along with the draft statute to the General Assembly. The situation in Palestine was becoming even more chaotic when the Security Council met on 1 April 1948 it adopted Resolution 43 (1948), calling for an "immediate truce be effected in Palestine" and for "the Jewish Agency for Palestine and the Arab Higher Committee to make representatives available to the Security Council for the purpose of arranging a truce between the Arab and Jewish communities of Palestine; and emphasizes the heavy responsibility which would fall upon any party failing to observe such a truce". The Security Council adopted Resolution 44 (1948), invoking Article 20 of the U.N. Charter on 1 April 1948 where the Security Council requested the Secretary-General to convoke a special session of the General Assembly to consider further the future of the government of Palestine. By 17 April 1948 the situation in Palestine had deteriorated further and the Security Council adopted Resolution 46 (1948), calling upon all persons and organizations in Palestine to immediately cease all military activities, as well as acts of violence, terrorism and sabotage; to refrain from any actions endangering the safety of the Holy Places in Palestine and refrain from importing or acquiring or assisting or encouraging the importation or acquisition of weapons and war materials (

). It also requested the government of the U.K., as the Mandatory Power, to supervise the execution of those measures and to keep the Security Council and the General Assembly informed on the situation in Palestine. The General Assembly then convened for its second special session between 16 April to 14 May 1948, during which it considered a working paper submitted by the United States (U.S.) on the question of the "Trusteeship of Palestine", which was opposed by the

. The assembly adopted resolution 185 (S-2) of 26 April 1948, asking the Trusteeship Council to study measures for the protection of Jerusalem, its inhabitants and to submit proposals to the General Assembly. On 14 May 1948, the assembly adopted Resolution 186 (S-2), which affirmed its support for the efforts of the Security Council to secure a truce in Palestine. The assembly also decided to appoint a U.N. Mediator to Palestine and specified the functions of the mediator, relieving the Palestine Commission from further "exercise of responsibilities" under resolution 181 (II). Bernadotte was appointed Mediator. After receiving proposals from the Trusteeship Council, the assembly adopted Resolution 187 (S-2), recommending to the Mandatory Power the appointment of a Special Municipal Commissioner for Jerusalem. The Jewish state of Israel was proclaimed on 14 May 1948, taking effect at midnight that day, as the British mandate expired the following day. The U.S. had proposed the establishment of a trusteeship for Palestine; nevertheless, the U.S. government recognized the Jewish state as did the U.S.S.R. The

On 22 May 1948, the Security Council adopted Resolution 49 (1948), calling for an abstention from any hostile military action in Palestine.

threatened Chapter VII intervention. To enforce the first of two truces, lasting four weeks, the United Nations then established an observer formation, with members drawn from Belgium, France, and the United States. On 6 July the UN observers had their first casualty with the death of the French Observer Commandant Rene de Labarriere, who was wounded near the Afoula area and later died in the Jewish Hospital at Afoula. He was wounded while investigating an alleged violation of the truce provisions by Jewish forces. The mediator was instructed on 29 May 1948 to create a one-month truce in Palestine. The mediator concept was teamed with the Truce Commission for supervisory over-watch of the Truce Plan. The month-long truce went into effect on 11 June 1948. On the same day, the first group of 36 observers arrived via

, Egypt, and continued to arrive for the next three days. The first truce did not last long due to widespread violence. As a result, the observers were withdrawn on 9 July 1948. The second truce, indefinite in length, was called by the United Nations Security Council on 15 July 1948. This declaration was to be put into effect on 18 July 1948. It was from Security Council Resolution 54 that the mediator was instructed to supervise the observance of the truce and to establish procedures for examining alleged breaches of the truce since 11 June 1948, and authorized the mediator to deal with breaches so far as it was within the capacity of the mediator to do so by appropriate local action. The Security Council Resolution 54 also requested the mediator to keep the Security Council informed concerning the operation of the truce and, where necessary, to take appropriate action. During the autumn of 1948, UNTSO was re-established with an increase in size to supervise the Second Truce. The first group of observers to serve in Palestine under the UN Mediator, Bernadotte, arrived in Rhodes on 20 July. It included 41 Americans and about 25 Belgians and were deployed on 21 July 1948. The initial group was quickly expanded to 93 in total because of the large area that had to be covered. As the number of personnel grew, the

The General Armistice Agreements (GAAs) came out of the mediator-chaired talks.

1949 to 1956

The period from August 1949 to June 1956 was initially chaotic but quickly settled into a routine of complaints on the Jordanian, Egyptian, Syrian and Lebanese fronts. It was initially possible for the UN personnel to deal with complaints of violations of the "truce" at the local commander level. As time progressed there arose a culture of claim and counter claim by the participating parties and regardless of the work and intent of UNTSO the intensity of the violent incidents increased. The GAAs had been hastily prepared in anticipation of an early peace along the lines of the 1947 Partition Plan and the primary concern was an end to the bloodshed at the earliest opportunity. As a result, the armistice lines had laid out temporary boundaries without thought to existing village boundaries or water rights. The armistice agreements were of a purely military character, intended to provide a transitional stage between the truce and a final peace. They constituted, in effect, non-aggression agreements of unlimited duration, but they contained in themselves no provision for establishing normal relations between the neighbouring countries. The armistice lines did not follow the fighting lines in all cases especially the Syrian Armistice line. In the case of the Egyptian Armistice line Israel forces carried on with a push south arriving at Umm Rashrash (Eilat) in March after the Egyptian-Israel GAA of 24 February 1949. This caused friction on setting the "truce lines". The contribution toward the foundation of a peaceful existence by the

For approximately 18 years (from 1949 until after the 1967 war), lack of harmony within the MACs was typical of the relationship existing between the countries. With the exception of the Israeli-Lebanon MAC, strife and discord became common. The MACs were very different from one another, bringing about four unique peacekeeping missions under the head of the UNTSO. Disputes on the Israel/Syria Mixed Armistice Commission (ISMAC) centred on the most precious Middle Eastern commodity: water and sovereignty of the DMZ. Contentious issues in the HKJIMAC principally concerned the divided city of Jerusalem, the Israeli

and the Chief of Staff UNTSO attempted to secure the implementation of a plan for withdrawal of Israeli armed forces and the removal of Egyptian forces from prohibited positions.

It also prohibited Egypt from maintaining positions in an adjoining area west of the demilitarized zone, and limited the arms and troops in the Defensive Areas on both sides of the Line. Both Egypt and Israel had indicated to the Secretary-General their willingness to comply fully with these two articles, within the framework of a return to full compliance with the Armistice Agreement. The Israeli Government gave assurances of its complete acceptance in principle of the plan. The agreed withdrawal, however, never took place.

, by providing a group of trained military personnel for peacekeeping and emergency operations to UNEF. Israel, after the 1956 war, subsequently ceased all cooperation/participation in its Israeli-Egyptian MAC. On 8 November, the Israeli representative informed the Secretary-General that his Government would withdraw its forces from Egypt immediately after the conclusion of satisfactory arrangements with the United Nations in connection with the Emergency International Force. As a result, according to the United Nations, arrangements were made through which, "without any change of the legal structure or status of the United Nations Truce Supervision Organization, the functions of UNTSO in the Gaza area were placed under the operational control of UNEF". A close co-operation between UNTSO and UNEF was to be maintained. The General Assembly, on 19 January 1957, noted "with regret and concern the failure of Israel to withdraw from Egyptian territory". Later, on 2 February 1957, the council deplored the" non-compliance of Israel with regard to completion of its withdrawal and called upon Israel to complete its withdrawal without delay". On 6 March 1957, General Burns was able to report to the Secretary-General of the UN that the "United Nations Emergency Force troops are now in position in all camps and centres of population in Gaza Strip". The staged withdrawal of Israeli forces from the

area was effected at the same time. In the following years, the Israel-Egypt MAC remained inactive, with only Egyptians and UN personnel taking part. In this period, the Lebanese sector was relatively calm compared to subsequent events in that area. The Israel-Lebanon MAC met regularly and had developed a routine for handling incidents that occurred. In the Jordanian and Syrian sectors were the scene of frequent and often serious incidents and both the Israel-Jordan and the Israel-Syria MAC's were quite active in pursuance of their mandate in responding to issues, with several incidents evolving regarding land use around Jerusalem and in the Hula area, and the movement of supply convoys to the Israeli enclave at Mount Scopus. During one of these incidents around Mount Scopus, a military observer, Canadian Lieutenant Colonel George Flint, was killed. In response to Israeli activities in the DMZ between the armistice demarcation lines in the Government House area in Jerusalem, Jordan complained to UN. This resulted in the Security Council adopting Resolution 127 (1958) on 22 January 1958, noting that the status of the zone is affected by the provisions of the Israel-Jordan GAAs and that neither Israel nor Jordan enjoys sovereignty over any part of the zone and directing the Chief of Staff of UNTSO in Palestine to regulate activities in the zone. In June 1958, UNTSO personnel were used to quickly raise the

. On 17 March 1961, the Israelis undertook a dress rehearsal for a military parade in the Israeli-occupied part of the Jerusalem, in which heavy military armaments were displayed. In response, Jordan complained to the MAC. On 20 March 1961, the Mixed Armistice Commission decided that "this act by Israel is a breach of the General Armistice Agreement". The MAC also condemned the parade and called upon the Israeli authorities to take the strongest measures to prevent a recurrence of such a breach of the GAA and to refrain in the future from bringing to Jerusalem any equipment that was in excess of that allowed for under the terms of the GAA. The Israeli authorities still contemplated holding the full dress military parade on 20 April 1961 in the Israeli-occupied part of Jerusalem. The Security Council, on 11 April 1961, adopted Resolution 162 (1961); this endorsed the 20 March 1961 decision of the MAC; relating to the military parade contemplated for 20 April 1961 in the Israel-occupied part of Jerusalem, and urged Israel to comply with the decision of the MAC made on 20 March 1961. The Israel-Syria Armistice Agreement provided for a demilitarized zone (DMZ) in the Hula Lake area at the foot of the Golan Heights, a zone which encompassed the area of Palestine as defined in the League of Nations Mandate occupied by Syrian forces at the time of the armistice. Civilian construction and land use in the DMZ caused numerous incidents around this time due to disputes over land ownership even though UNTSO was tasked with attempting to regulate activities leading to such disputes in the zone. After heavy fighting broke out between Israel and Syria in the DMZ, the Security Council in Resolutions 92 (1951) and 93 (1951) of 8 and 18 May 1951 called upon the parties to cease fighting and endorsed the request of the Chief of Staff of UNTSO that the Israeli company involved be instructed to cease all operations in the DMZ until such time as an agreement is arranged through the Chairman of the MAC for continuing its project. In Resolution 111 (1956) of 19 January 1956, the Security Council dealt with the confrontation which had escalated following interference by the Syrian authorities with legitimate Israeli activities on Lake Tiberias. It condemned as "in no way justified" the Israeli action taken in response to that interference in the form of an attack by Israeli regular army forces against Syrian regular army forces on Syrian territory. It also noted that in violation of the provisions of the General Armistice Agreement concerning the DMZ, the Zone had been crossed by the Israeli forces that entered Syria. Following a prolonged military confrontation between the parties, the Security Council was again involved in the Israel – Syria situation in 1962 in the light of a report by the Chief of Staff of UNTSO on the military activities in the Lake Tiberias area and in the DMZ. The council in Resolution 171 (1962) of 9 April 1962 noted with satisfaction that a cease fire had been achieved. It deplored the hostile exchanges which had taken place and called upon the governments concerned to comply with the General Armistice Agreement. It determined that an Israeli attack on 16–17 March had been a flagrant violation of the previous resolution (111), and called on Israel scrupulously to refrain from such action in the future. It also called upon both parties to abide scrupulously by the cease fire arranged by the Chief of Staff of UNTSO, and called specifically for strict observance of the article of the GAA which provides for the exclusion of armed forces from the demilitarized zone, and of the annex to the GAA which sets limits on forces in the defensive area.

agreements which included new boundaries between the countries. Even though there was no change to UNTSO's mission, the execution of its original mission became nearly impossible with the advent of the newly drawn ceasefire lines between Israel and Egypt-Jordan-Syria respectively. Additionally, UNTSO did not have the MACs to supervise since Israel abrogated its initial agreement to the Armistice as conceived. Realizing the changing political situation, the UN Security Council added some new tasks to the UNTSO Charter on the first few months following the 1967 ceasefire. Specifically, in the Egypt-Israel and Israel-Syria fronts, UNTSO established observation posts (OPs): a total of 15 were established along the Suez, while 16 were established in the Golan Heights. These posts remained in effect until the Yom Kippur War of October 1973. The UN offices established in

At the urging of the Lebanese government, UNTSO created an observation operation along the Lebanese border (1949 Armistice Demarcation line) in the spring of 1972. Due to the Palestinian activity in South Lebanon and the potential Israeli reprisal against their encampments, UNTSO felt the potential for further conflict warranted the additional OPs. At this time, posts were established at

Yom Kippur to the Israel–Lebanon War

As a result of the Yom Kippur War, the positions occupied by the UN military observers in the Middle East were drastically affected. A total of eight OPs were abandoned at this time; however, most OPs are still located in the same place today. In the Egyptian-Israeli sector, UNTSO personnel were structured around the Observer "Group" concept and placed under the UN Peace-Keeping Forces that occupied the region. Observer Group Sinai was formed and attached to the Second United Nations Emergency Force (UNEF II). The Charter for UNEF II expired on 24 July 1979 which only left UNTSO's presence. The observers were then restructured on new OPs which were located on vantage points throughout the Sinai peninsula. For the Sinai Group, their main office was located in Cairo (in 1993 it was moved to Ismailia, closer to the OPs). On the Israeli-Syria border, UNTSO's ceasefire observation and supervision mission continued but with a readjusted ceasefire line. Observer Groups Damascus and Golan (Syrian sector) were established as a result of the United Nations Disengagement Observer Force (UNDOF). Shortly after the 1973 war, U.S. participation in UNTSO expanded to twenty-five officers. The

s—the Soviet participation was set at the same level as the United States (which was twenty-five each at that time). Subsequent to the 1973 agreement, the number of observers for all countries participating increased. As a result, the number of personnel to be provided by Soviet Union and the United States was re-established at thirty-six each. Since U.S. personnel were not allowed in Lebanon (a limitation set forth by U.S. Secretary of Defence

, due to the threat to U.S. personnel), at this time there was a move to reduce U.S. participation to UNTSO. As a corollary, this also required a reduction in the numbers of Soviet observers. This reduction was delayed due to a lengthy diplomatic process.


After the Lebanon War

The Israeli-Lebanese conflict commenced in the late 1970s, ending the relative stability of the demarcation line along that front. It provided the latest major change to UNTSO's structure. After the outbreak of the

Contributing countries

Military personnel allocated to UNTSO have come from many nations over the course of the mission's history. The United States, Belgium and France provided the initial groups of observers until 1953, but as the Cold War developed the number of personnel committed by the US and France was reduced. From 1953, other nations began contributing observers. Notably, Sweden has provided the most number of chiefs of staff. The Soviet Union first deployed personnel after the 1973 Arab–Israeli war. In 2020, the following nations contributed personnel:

Today

UNTSO personnel have also been available at short notice to form the nucleus of other peacekeeping operations. The availability of UNTSO's military observers for almost immediate deployment after the Security Council had acted to create a new operation has been an enormous contributory factor to the success of those operations. According to the United Nations, "the military observers are unarmed and they carry out their jobs by observing and reporting violations of the agreements of ceasefire, disengagement etc. that are relevant to their area of operations. All military observers are seasoned officers of the rank of captain or major coming from all branches of service in their respective countries armed forces. The military observers work in multi-national teams, so that any observations will always be confirmed by at least two observers from different nations, as a measure to ensure impartiality". UNTSO currently provides military observers to three different UN missions in the area: Observer Group Lebanon (OGL), supporting UNIFIL in
