The Multinational Force & Observers (MFO), headquartered in Rome, is an independent international organization, created by agreement between the Arab Republic of Egypt and the State of Israel, with peacekeeping responsibilities in the Sinai. The origins of the MFO lie in Annex I to the 1979 Treaty of Peace between Egypt and Israel, in which the 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 parties negotiated a Protocol in 1981 establishing the MFO "as an alternative" to the envisioned UN force.
