An increasing number of experts, including those appointed by a U.N. body, say Israel's offensive in Gaza constitutes genocide, further isolating the country internationally and threatening its standing even with longtime allies.

Israel vehemently denies the accusation, and some have rejected it or said only a court can make that determination.

Even so, global outrage over Israel’s wartime conduct has mounted in recent months, as images of starving children emerged, adding to the humanitarian catastrophe of a 23-month war that has killed thousands of Palestinians and laid waste to much of Gaza.

A current offensive in the territory's largest city further raised concern, with some of Israel's European allies condemning it.

But the genocide accusation goes further, raising the question of whether a state forged in the aftermath of the crime is now committing it.
