In November 1947, the United Nations General Assembly endorsed a plan for the partition of the then British Mandate of Palestine, providing for the creation of an Arab State and a Jewish State, with Jerusalem to be placed in Trusteeship with international status. The plan was not accepted by the Palestinian Arabs and Arab States and only partially accepted by the Jewish Agency of Palestine. On 14 May 1948, the United Kingdom relinquished its mandate over Palestine and the State of Israel was proclaimed. On the following day, the Palestinian Arabs, assisted by Arab States, entered into a state of hostilities against Israel when the Arab League forces under the command of King Abdullah I of Jordan entered the Palestine Mandated area into the territory allotted for the Arab partition.
On 29 May 1948, UN Security Council Resolution 50 (1948), called for a cessation of hostilities in Palestine and decided that the truce should be supervised by the UN Mediator, Count Folke Bernadotte of Wisborg, with the assistance of a group of military observers. The first group of military observers, which has become known as the United Nations Truce Supervision Organization (UNTSO), arrived in the region in June 1948, when the Security Council threatened Chapter VII intervention. To enforce the first of many truces, lasting four weeks, the UN then established an observer formation, with members drawn from Belgium, France, and the United States. On 6th July the UN observers had their first casualty with the death of the French Observer Commandant Rene Labarriere, he 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.In 1949, UNTSO military observers remained to supervise the 1949 Armistice Agreements between Israel and its Arab neighbours, which were for many years the main basis of the uneasy truce in the whole area.
The Mediator was instructed on May 29, 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. As a result, the Mediator and the Truce Commission would be provided with a number of military observers which set a precedence for today's assignment of UNMO's (United Nations Military Observers) in the Middle East.
The month-long truce went into effect on June 11, 1948. On the same day, the first group of 36 observers arrived via Cairo, Egypt and continued to arrive for the next three days. The first truce did not last long due to widespread violence which again erupted. As a result, the observers were withdrawn on July 9, 1948. The second truce, indefinite in length, was called by the United Nations Security Council on July 15, 1948. This declaration was to be put into effect on July 18, 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, also the Security Council Resolution 54 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, Count Folke Bernadotte, arrived in Rhodes at 6 P.M. GMT 20 July. It included 41 Americans and about 25 Belgians and were deployed on the 21 July 1948. The initial group was quickly expanded to 93 in total because of the tremendous area that had to be covered. As the number of personnel grew, the United Nations Secretariat (of Personnel) supported the creation of the United Nations Truce Supervision Organization (UNTSO), the same organization UN Military Observers are assigned to today. Initially, the command was headed by a Chief-of-Staff (a general officer from one of the participating countries) in accordance with the personal direction of the Mediator, (a civilian).
Talks between the warring parties began under the supervision of the Acting Mediator, Ralph Bunche, as the UN Mediator, Count Folke Bernadotte, had been assassinated on September 17, 1948. The General Armistice Agreements (GAAs) came out of the Mediator-chaired talks. UNTSO's activities have been and still are spread over territory within five States, and therefore it has relations with five host countries -- Egypt, Israel, Jordan, Lebanon and Syrian Arab Republic. Since then, UNTSO has also supervised the General Armistice Agreements of 1949 and the observation of the ceasefire in the Suez Canal area and the Golan Heights following the Six-Day War of June 1967.
On 11 August 1949 it was decided by the Security Council that the mediators function had been completed and that the role in observing the ceasefire should be passed to the Chief of Staff of the UNTSO
UNTSO has offices in Beirut and Damascus.
Sixty years ago on that date, the United Nations Security Council established the first peacekeeping operation, the United Nations Truce Supervision Organization (UNTSO), based in the Middle East. In 2001, the General Assembly proclaimed 29 May as the International Day of United Nations Peacekeepers to pay tribute to the men and women who serve in United Nations peacekeeping operations and honour the memory of those who have lost their lives in the cause of peace.
On 14 May 1948, a Jewish state, Israel is proclaimed, one day before the mandate expired and just before the General Assembly began a discussion on the main resolution containing the U.S. idea on the trusteeship of Palestine. The U.S. government recognizes the Jewish state as does the U.S.S.R. War breaks out in Palestine. Several Arab armies engaged the Jewish forces of the Provisional Government of Israel.
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 Mount Scopus enclave, the Latrun salient (sovereignty of the DMZ), Arab infiltration across the armistice demarcation line and large scale Israeli military incursions into Jordanian territory. The troubles soon bloomed the Infiltration by the displaced Arabs, followed by raids of reprisal and intimidation by the Israelis, soon had the borders crackling with tension.The infiltration by Palestinians was initially unarmed groups crossing to regain possessions, harvest their crops or visit relatives; later infiltrations became armed individuals and then progressing into small retaliatory raids. As Pasha Glubb explained:-
Some deep psychological urge which impels a peasant to cling to and die on his land. A great many of these wretched people are killed now, picking their own oranges and olives just beyond the line. The value of the fruit is often negligible. If the Jewish patrols see him he is shot dead on the spot, without questions. But they will persist in returning to their farms and gardens.Israeli infiltration into Jordanian Territory being organised retaliatory raids by military units such as occurred at Qibya and Nahhalin raids. Israel’s frustration with the UN and the other parties led to their withdrawal from ISMAC in 1951 and HKJIMAC in 1954. The functioning of the Israel Lebanon MAC remained smooth due to the more relaxed attitude of the Israeli patrols towards returnees and infiltrators. Disputes with Egypt, who banned Israel-bound shipping from the Suez Canal and blockaded the Gulf of Aqaba, pertained to the al-Auja DMZ. By 1955, Israel ceased attending the Egyptian MAC and stepped up raids into the Gaza Strip and Sinai to which Egypt retaliated by sponsoring the Palestinian fedayeen (self-sacrificer) raids. From 21 September 1955, the Egypt/Israel Demilitarized Zone was occupied by Israel armed forces, the UN Secretary-General Dag Hammarskjöld and the Chief of Staff UNTSO had engaged in efforts to secure the implementation of a plan for withdrawal of Israel armed forces and removal of Egyptian Forces from prohibited positions. Articles VII and VIII of the Egypt-Israel GAA established a Demilitarized Zone (DMZ) centred on El-Auja and forbade the presence of armed forces it also prohibited Egypt from maintaining defensive 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 Israel Government gave assurances of its complete acceptance in principle of the plan. The agreed withdrawal, however, never took place. Full compliance with the Armistice Agreements was incompatible with the invocation of a state of war. The full-scale 1956 invasion of Egypt by British, French and Israeli forces, The invasion followed Egypt's decision of 26 July 1956 to nationalize the Suez Canal after the withdrawal of an offer by Britain and the United States to fund the building of the Aswan Dam. The invasion demonstrated UNTSO’s irrelevance in the final settlement to the full and lasting peace.
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 the 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 Gaza Strip, with the exception of an Israel troop unit at Rafah camp, at 0400 GMT on the 7 March 1957 was carried out according to plan and without incidents. By agreement, that last Israel element was withdrawn by 1600 GMT on 8 March and a full Israeli withdrawal from the Sharm al Shaikh area was effected at the same time.
In response to activities conducted by Israel in the DMZ between the armistice demarcation lines in the area of Government House in Jerusalem Jordan complaints 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. The sovereignty issues in the DMZs was never the sphere that the UNTSO could arbitrate on, as the UNTSO was purely a military organisation for maintaining a truce.
Following a dress rehearsal on 17 March 1961 for a Military parade in the Israeli-occupied part of the Holy City of Jerusalem, in which heavy military armament took part 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 this act by Israel 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 the Holy City 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. This showed that the MAC concept still had complete support of the United Nations
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. These posts remained in effect until the Yom Kippur War of October 1973. The UN offices established in Amman and Gaza (before the 1967 War) were allowed to continue to function as Liaison Offices, even though the MAC concept had became defunct.
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 observation posts.
Shortly after the 1973 War, U.S. participation in UNTSO expanded to twenty-five officers. The U.S. Marine Corps portion was six. Approximately the same period, the Soviets made a surprise move and announced their support of UNTSO and likewise wanted to provide Observers. To keep a balanced presence between the East-West Superpowers--the Russian 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 (which still remains today). Since U.S. personnel are not allowed in Lebanon, (a limitation set forth by U.S. Secretary of Defence Frank Carlucci, due to the threat to U.S. personnel), there is a current move to reduce U.S. participation to UNTSO. Likewise, the Soviets would have to drop its participation to the same number as the United States. Due to the lengthy diplomatic process, this proposal has not been acted upon by both nations yet. However, the proposal is anticipated to receive favourable consideration.
The military observers are un-armed 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 Ssouthern Lebanon, Observer Group Golan (OGG) supporting UNDOF in the Golan Heights and Observer Group Egypt (OGE) in the Sinai Peninsula.
OGG, who has its headquarters co-located with UNDOF HQ in Camp Faouar in Syria, is split into two outstations; OGG-D (Observer Group Golan - Damascus) based in Damascus, Syria and OGG-T (Observer Group Golan - Tiberias) based in Tiberias, Israel. Each outstation mans a number of observation posts on each side of the [[]Area of Separation]] (AOS) that was put in place as part of the 1974 Disengagement Agreement between Syria and Israel following the 1973 Yom Kippur War. The military observers carry-out fortnightly inspections inside the Area of Limitations (AOL) to verify, that both sides adhere to the limitations on troop levels and military equipment within 10, 20 and 25 km zones from the AOS as prescribed by the 1974 Disengagement Agreement.
OGL HQ are co-located with UNIFIL HQ in Naquora, Southern Lebanon. OGL mans four patrol bases along the "Blue Line" - a demarcation line between Israel and Lebanon.
OGE is based in Ismalia by the Suez Canal in Egypt. OGE conducts short and long-range patrols in the Sinai Peninsula.
