The Sabra and Shatila massacre, which took place on 16–18 September 1982 in the Sabra and Shatila Palestinian refugee camps in Beirut, Lebanon, is considered the major dark spot in Hobeika's career. The massacre was carried out by Lebanese Phalangist militia members, under the control of Hobeika, against the Palestinians and Lebanese Shia Muslims who had taken refuge in the camps.
