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 Amman and Gaza (before the 1967 War) were allowed to continue to function as Liaison Offices, even though the MAC concept had become defunct.
