In September 1988, the Parliament failed to elect a successor to President Gemayel as a result of differences between the Christians, Muslims, and Syrians. The Arab League Summit of May 1989 led to the formation of a Saudi–Moroccan–Algerian committee to solve the crisis. On 16 September 1989 the committee issued a peace plan which was accepted by all. A ceasefire was established, the ports and airports were re-opened and refugees began to return.
