Nine days before he was to take office , on September 14 , 1982 , Bachir was killed along with 25 others in a bomb explosion in the Kataeb headquarters in Achrafieh . The attack was carried out by Habib Shartouni , a member of the Syrian Social Nationalist Party ( SSNP ) , believed by many to have acted on instructions of the Syrian government of President Hafez al-Assad . The next day , Israel moved to occupy the city , allowing Phalangist members under Elie Hobeika 's command to enter the centrally located Sabra and the Shatila refugee camp ; a massacre followed , in which Phalangists killed between 762-3,500 ( number is disputed ) civilians , mostly Palestinians and Lebanese Shiites , causing great international uproar
