Thirty-three years ago on 16 September 1982, the Lebanese Christian Phalange militia entered the Palestinian refugee camps of Sabra and Shatila in Beirut. Israeli forces occupied the surrounding city and allowed the militia’s entry into the camp. Over the following three days, at least 800 civilians were massacred as Israeli-manned checkpoints turned back fleeing Palestinians and Israeli troops fired flares to illuminate the camp at night. The massacre made international headlines and remains a painful memory in Palestinian history. The Journal of Palestine Studies has published several papers and articles on the massacre that we have made available in a Special Focus.
