Sabra and Shatila massacre
On 15th September, the Israeli army was the first power to occupy Sabra and Shatila, closing all access out of the camps and effectively confining thousands of civilians and refugees inside. From 16th to 18th September 1982, the camps were then subjected to an onslaught of violence, rape, abuse, and mass murder. Other groups became involved in carrying out the decimation, including the Lebanese Forces and other right-wing militias. The massacre was an enormous loss of human life, consisting of almost entirely Palestinian refugees and Lebanese civilians, including many women and children, hospital patients, and public servants such as medical staff. There is still uncertainty as to precisely how many were killed in the massacre; some state the death toll to be as low as 300, some claim it's nearer to 1,700, while other estimates range as high as 4,500 victims. Most sources posit that at least 3,000 innocent people were murdered in this 3-day period.
