September 16, 1982: Christian militiamen massacre hundreds at the Sabra and Shatila Palestinian refugee camps in Lebanon.
Lebanese Christian Maronite president-elect Bashir Gemayel is assassinated. Two days later, Christian militias allied with Israel against the PLO enter the Sabra and Shatila refugee camps in Beirut and massacre some 800 unarmed Palestinians. The Kahan Commission (an Israeli commission of inquiry) finds that Defense Minister Ariel Sharon bears personal responsibility because he did not order 'appropriate measures for preventing or reducing the chances of a massacre.' As a result, Sharon gave up his defense portfolio but remained in the cabinet.
