Changes

Full-scale civil war broke out in April 1975. After shots were fired at a church, gunmen in Christian East Beirut ambushed a busload of Palestinians. Palestinian forces joined predominantly leftist-Muslim factions as the fighting persisted, eventually spreading to most parts of the country and precipitating the Lebanese President's call for support from Syrian troops in June 1976. In fall of 1976, Arab summits in Riyadh and Cairo set out a plan to end the war. The resulting Arab Deterrent Force, which included Syrian troops already present, moved in to help separate the combatants. As an uneasy quiet settled over Beirut, security conditions in the south began to deteriorate.

After a PLO attack on a bus in northern Israel and Israeli retaliation that caused heavy casualties, Israel invaded Lebanon in March 1978, occupying most of the area south of the Litani River. In response, the UN Security Council passed Resolution 425 calling for the immediate withdrawal of Israeli forces and creating the UN Interim Force in Lebanon (UNIFIL), charged with maintaining peace. Israeli forces withdrew later in 1978, turning over positions inside Lebanon along the border to their Lebanese ally, the South Lebanon Army (SLA) under the leadership of Maj. Sa'ad Haddad, thus informally setting up a 12-mile wide "security zone" to protect Israeli territory from cross border attack.
