UNITED NATIONS AND NATO RESPONSE FORCE MULTINATIONAL FORCE LEBANON PATCHES Grouping of 4 patches. Multinational Force in Lebanon Patch: The Multinational Force in Lebanon (MNF) was an international peacekeeping force created in August 1982 following a 1981 U.S.-brokered ceasefire between the Palestine Liberation Organization (PLO) and Israel to end their involvement in the conflict between Lebanon's pro-government and pro-Syrian factions. The ceasefire held until June 3, 1982, when the Abu Nidal Organization attempted to assassinate Shlomo Argov, Israel's ambassador to London.[4] Israel blamed the PLO and three days later invaded Lebanon. West Beirut was besieged for seven weeks before the PLO acceded to a new agreement for their withdrawal. The agreement provided for the deployment of a Multinational Force to assist the Lebanese Armed Forces in evacuating the PLO, Syrian forces and other foreign combatants involved in Lebanon's civil war.
