On this day in 1982, Beirut was besieged by the Israeli army and Palestinian leader Yasser Arafat boarded a ship that took him to his new exile in Tunisia. The Palestinian Liberation Organization’s loss of its last front with Israel would leave its mark on the Palestinians and Lebanon. As Israel tightened its siege of Beirut, Arafat took a secret decision to carry on fighting for six months until regional and international stances emerged. He was forced to leave Lebanon after 88 days, marking an end of what he described as the “longest Arab-Israeli war.”
