but also in the south). On April 15, 1985, Amal and the PSP attacked Al-Murabitun, the main Lebanese Sunni militia and the closest ally of the PLO in Lebanon. Al-Murabitun were vanquished and their leader, Ibrahim Kulaylat was sent into exile. On May 19, 1985, heavy fighting erupted between Amal and the Palestinians for the control of the Sabra, Shatila and Burj el-Barajneh camps (all in Beirut). On May 28, 1985, Amal suffered a suicide attack by four young female Palestinian suicide bombers in Shatila. Despite its efforts, Amal could not take the control of the camps. The death toll remains unknown, with estimates ranging from a few hundreds to a few thousands. This and heavy Arab pressure led to a cease-fire on June 17. Second battle (May 1986) The situation remained tense and fights occurred again in September 1985 and March 1986. On May 19, 1986, heavy fighting erupted again. Despite new armaments provided by Syria, Amal could not take control of the camps. Many cease-fires were announced, but most of them did not last more than a few days. The situation began to cool after Syria deployed some troops on June 24, 1986. Third battle (September 1986) There was tension in the south, an area where Shi'as and Palestinians were both present. This led to frequent clashes. On September 29, 1986, fighting erupted at the Rashidiyye camp (Tyre). The conflict immediately spread to Sidon and Beirut. Palestinian forces managed to occupy the Amal-controlled town of Maghdouché on the eastern hills of Sidon to open the road to Rashidiyye. Syrian forces helped Amal and Israel launched air strikes against PLO position around Maghdouche. A cease-fire was negotiated between Amal and pro-Syrian Palestinian groups on December 15, 1986, but it was rejected by Yasser Arafat's Fatah. Fatah tried to appease the situation by giving some of its positions to Hezbollah and to the Murabitun. The situation became relatively calm for a while, but the bombing against the camps continued. In Beirut, a blockade of the camps led to a dramatic lack of food and medications inside the camps. In early 1987, the fighting spread to Hezbollah and the PSP who supported the Palestinians. The PSP, having won numerous battles, quickly seized large portions of west Beirut. Consequently, Syria occupied west Beirut beginning February 21, 1987. On April 7, 1987, Amal finally lifted the siege and handed its positions around the
