The U.N. rights office said on Friday it had recorded at least 798 killings within the past six weeks at aid points in Gaza run by the U.S.- and Israeli-backed Gaza Humanitarian Foundation and near convoys run by other relief groups.

Out of 251 hostages seized in the attack, 49 are still held in Gaza, including 27, the Israeli military says, are dead. At least 57,823 Palestinians, most of them civilians, have been killed since the start of the war, according to the health ministry in Hamas-run Gaza.

Ten Palestinians were reported killed Friday waiting for rations in Gaza, adding to the nearly 800 killed seeking aid in the last six weeks, according to the UN, with Israel’s army saying it issued troops new instructions following the repeated reports of deaths.
