“Her father is a Lebanese Forces supporter, she says. She got the cross on her wrist two years ago, after the October 2012 Beirut bombing, in support of her father, “to show him, ‘I’m on your side.'”

This situation was remedied by the Kataeb Regulatory Forces (most notably the BG Squad that was led by Bachir) and their allied Christian militias as they besieged the Palestinian camps embedded in Christian East Beirut one at a time and brought them down. The first was on 18 January 1976 when the heavily fortified Karantina camp, located near the strategic Beirut Harbor, was invaded: About 1,000 PLO fighters and civilians were killed.[1] According to then-Washington Post-correspondent Jonathan Randal, "Many Lebanese Muslim men and boys were rounded up and separated from the women and children and massacred," while the women and young girls were violently raped and robbed.
