A resolution adopted by the United Nations Security Council on 19 March 1978 with a vote of 12 For, 0 Against, 2 Abstaining, 1 Absent. In response to Operation Litani, an Israeli military operation against PLO strongholds in southern Lebanon, the resolution called for an immediate ceasefire and the withdrawal of Israeli forces from Lebanon, and for the Lebanese government to exercise its sovereignty in the region. It also established the United Nations Interim Force in Lebanon (UNIFIL) to oversee its implementation. The Israeli withdrawal was completed in June 1978, but four years later Israel invaded Lebanon again at the start of the 1982 Lebanon War. Following the final Israeli withdrawal in May 2000, on 16 June 2000 the Security Council confirmed that Israel had fulfilled its obligations under the resolution.
