Siege of Deir al-Qamar

As early as September 4, 1983, the Christian population started fleeing their villages, some heading toward the Christian town of Deir al-Qamar in the Shuf and others toward Beirut, Jezzine, or the Beqaa. Approximately 8,000 Christians from more than 60 villages sought refuge in Deir al-Qamar, in the Shuf. Several hundred LF fighters had also sought refuge there.

Around September 7, 1983, the PSP and its allies began a siege of the town that lasted until December 15, 1983.During the siege, shelling, gunfire, and various tactics were used to scare the refugees as well burning houses in nearby villages, and making threats through loudspeakers.
