"On April 7, senior Palestinian official Saeb Erekat suggested to CNN that some 500 Palestinians had been killed in the camp. Five days later, when the fighting stopped, PA Secretary Ahmed Abdel Rahman told UPI that the number was in the thousands, hinting, along with other Palestinian figures, that Israel had snatched bodies, buried Palestinians in mass graves and under the rubble of ruined buildings, and otherwise conducted on a scale compatible with genocide."
Stories of hundreds of civilians being killed in their homes as they were demolished spread throughout international media.[8] Subsequent investigations found no evidence to substantiate claims of a massacre, and official totals from Palestinian and Israeli sources confirmed between 52 and 54 Palestinians, mostly gunmen, and 23 IDF soldiers as having been killed in the fighting."
