Almog Meir Jan, Noa Argamani, Andrey Kozlov and Shlomi Ziv were kidnapped from the Nova festival in southern Israel on Oct 7.
Hamas-run Gaza’s health ministry said at least 274 Palestinians were killed and 698 wounded during the operation.
“Hundreds of Palestinians, many of them civilians, were reportedly killed and injured,” Laurence said.
“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.”
