United Nations Truce Supervision Organisation

18 December 1958 to date

UNTSO, established in 1948, is the oldest ongoing United Nations peacekeeping operation. It operates in Syria, Jordan, Lebanon and Israel - the parties to the Truce Agreements that followed the fighting in Palestine in 1948.

The mission's mandate, “to observe and maintain any truce or ceasefire demanded by the Security Council and to assist the parties in supervising any agreements concluded by them,” is open-ended and does not require periodic renewal.

UNTSO is also tasked with assisting in the setting up of new UN peacekeeping missions and has been involved in the establishment of many of these, including ONUC, UNIFIL and UNPROFOR. UNTSO HQ is based in Jerusalem and has observers in Lebanon (OGL), Tiberias (OGG-T), and Damascus (OGG-D) as well as liaison officers in Cairo, Beirut, Amman and Gaza. UNTSO also supports the United Nations Disengagement Observer Force (UNDOF) on the Golan Heights by manning observation posts in the area.
