The U.N. human rights office said on Tuesday the killings of civilians in Gaza during the Israeli operation to free four hostages, as well as Palestinian armed groups' holding of captives in densely populated areas, could amount to war crimes.
The operation killed more than 270 Palestinians, according to Gazan health officials.
"The manner in which the raid was conducted in such a densely populated area seriously calls into question whether the principles of distinction, proportionality and precaution - as set out under the laws of war - were respected by the Israeli forces," Jeremy Laurence, spokesperson for the U.N. human rights office, said.
Laurence added that the holding of hostages in such densely populated areas by Palestinian armed groups was "putting the lives of Palestinian civilians, as well as the hostages themselves, at added risk from the hostilities."
"All these actions, by both parties, may amount to war crimes," he said.
In response to the statement, Israel's Permanent Mission to the United Nations in Geneva accused of U.N. High Commissioner for Human Rights of "slandering Israel".
"The toll of this war on civilians is first and foremost the product of Hamas's deliberate strategy to maximize civilian harm," the mission said.
The conflict in Gaza was triggered when Hamas fighters charged into Israel on Oct. 7 and killed some 1,200 people, according to Israeli tallies. Israel's subsequent bombardment and invasion of Gaza has killed more than 37,000 Palestinians, according to health authorities in the Hamas-run enclave.
Gunmen took around 250 hostages back to Gaza on Oct. 7, more than 100 of whom were released in exchange for about 240 Palestinians held in Israeli jails during a week-long truce in November.
There are 116 hostages left in the coastal enclave, according to Israeli tallies, including at least 40 whom Israeli authorities have declared dead in absentia.
