History of Israel's role in Lebanon
Israel fears attacks from across its border with Lebanon
Palestinian refugees have lived in camps in southern Lebanon since the state of Israel was created. The area became the centre of Palestinian political and military operations when Palestinian guerrilla forces were expelled from Jordan in 1970-1 following clashes with the Jordanian Arab Legion. Raids across the Israeli border by Palestinians from southern Lebanon became more frequent.
Under pressure from the UN Security Council, Israel withdrew from the territory, but transferred control of a border strip to the pro-Israeli Christian militias in Lebanon. The UN Security Council adopted Resolution 425, which called for the withdrawal of Israeli troops from south Lebanon and established a UN Interim Force in Lebanon (Unifil), to maintain peace across the border.
Israeli troops rapidly advanced, occupying the west of Beirut and trapping 6,000 Palestinians in the southwest of the country. US diplomatic effort eventually secured the dispersal of Palestinian fighters to other Arab countries.
In September 1982, the Phalangist Christian militia attacked Palestinian refugee camps at Sabra and Chatila in retaliation for the assassination of the Christian President-elect of Lebanon. Many of the inhabitants were massacred while Israeli forces stood by.
A peace agreement between Israel and Lebanon, signed in May 1983 called for an end to all hostilities and the withdrawal of all foreign troops from the country. It also provided for security arrangements for Israel in south Lebanon.
Israel redeployed its troops to the three to six mile wide "security zone" along the border in Southern Lebanon and has remained in control of the area ever since. Israel also armed the pro-Israeli Christian militia, the South Lebanon Army (SLA), to help it police the region.
The Israeli campaign failed to remove the PLO threat to its northern towns. Attacks by Palestinian guerrillas on Israel, and fighting between the Iranian backed Hezbollah forces and the pro-Israeli militias continued throughout the mid-1980s, until a cease-fire was agreed between the militias in September 1989.
In June 1991, Israel launched attacks on Palestinian bases in southern Lebanon, ostensibly in response to attacks by the Hezbollah guerrilla groups. Fighting escalated again in the autumn of 1992.
In April 1996, the Israeli armed forces launched an operation code-named "Grapes of Wrath", which was intended to wipe out Hezbollah's base in southern Lebanon. Critics of the operation accused the Israeli government of electioneering for a general election which was due in August. International condemnation greeted the massacre on 18 April 1996 of over 100 Lebanese refugees in a UN base at Qana, in what the Israeli military said was a mistake. A cease-fire was agreed between Israel and Hezbollah on 27 April 1996.
