The mission of the MFO is to supervise the implementation of the security provisions of the Egyptian-Israeli Treaty of Peace and employ best efforts to prevent any violation of its terms.
Article II of Annex I to the Treaty of Peace establishes four security zones, three in the Sinai in Egypt and one in Israel along the international border. Limitations on military forces and equipment within each zone are stipulated in Annex I to the Treaty.
The origins of the MFO lie in Annex I to the 1979 Treaty of Peace between Egypt and Israel, in which the Treaty Parties undertook to request the United Nations to provide a force and observers to supervise the implementation of the Treaty. When it did not prove possible to obtain Security Council approval for the stationing of a UN peacekeeping force in the Sinai, the Treaty Parties negotiated a Protocol in 1981 establishing the MFO “as an alternative” to the envisioned UN force.
