In January 1976, a Syrian proposal to restore the limits to the Palestinian guerrilla presence in Lebanon, which had been in place prior to the outbreak of the civil war, was welcomed by Maronites and conservative Muslims, but rejected by the Palestinian guerrillas and their Lebanese Druze-led and leftist allies. In June 1976, to deal with the opposition posed by this latter group (which was normally allied with Syria), Syria dispatched Palestinian units under its control into Lebanon, and soon after sent in its own troops as well. Syrian claims these interventions came in response to appeals from Christian villagers under attack by Leftists in Lebanon.
By October 1976, Syria had caused significant damage to the strength of the Leftists and their Palestinian allies, but at a meeting of the Arab League, it was forced to accept a ceasefire.
