The United Nations Truce Supervision Organization (UNTSO) is the oldest of all UN Peacekeeping missions which started its work in Egypt in 1948 with Observer Group Sinai. Following the signing of the historic Camp David Peace Accord between Egypt and Israel in 1979, Observer Group Egypt was established on 1 April 1980. Observer Group Egypt manned six observation outposts in the Sinai, located in Ismailia, El Arish, El Nakhl, El Melize, Abu Rudeis and St. Catherine, with its headquarters in Cairo. In March 1993, the headquarters relocated to Ismailia and the six observation posts were reduced to three, El Arish, El Melize and St. Catherine. Between July and October 1995 two observation posts (St. Catherine and El Melize) were closed. Finally, in November 1996, the last observation post in El Arish was closed leaving Observer Group Egypt to operate from its headquarters in Ismailia. The newly named Liaison Office to Cairo (LOC) was established on 26 September 2008 as result of a mission change from an Observer Group to a Liaison Office and operates in Egypt at the express invitation of the Egyptian Government. The Area of Operations for Liaison Office to Cairo (LOC) is the Sinai Peninsula and Cairo.
