On 18 April 1979 , Haddad proclaimed the area controlled by his force Independent Free Lebanon . The following day , he was branded a traitor to the Lebanese government and officially dismissed from the Lebanese Army . Another consequence of the Israeli invasion was the establishment in southern Lebanon of the United Nations Interim Force in Lebanon , whose mission was to separate the various combatants . Haddad 's militia collaborated with Israel and received the bulk of its arms , equipment , supplies and ordnance from Israel . There are eyewitness accounts that support the claim that Saad Haddad 's troops were involved in the massacres of Sabra and Shatila in 1982 . In the massacre an estimated 763 - 3,500 civilians were killed . In 1984 , Haddad died of cancer . His successor as the head of the SLA was general Antoine Lahad
