This report provides witness accounts of the devastating effects that white phosphorus munitions had on civilians and civilian property in Gaza. Human Rights Watch researchers in Gaza immediately after hostilities ended found spent shells, canister liners, and dozens of burnt felt wedges containing white phosphorus on city streets, apartment roofs, residential courtyards, and at a United Nations school. The report also presents ballistics evidence, photographs, and satellite imagery, as well as documents from the Israeli military and government.
