The General Armistice Agreements (GAAs) came out of the Mediator-chaired talks. On 11 August 1949, it was decided by the Security Council that the mediator's function had been completed and that the role in observing the ceasefire should be passed to the Chief of Staff of the UNTSO. 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. 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 following the Suez Crisis of 1956, and the Golan Heights following the Six-Day War of June 1967 and the Yom Kippur War of 1973.
