The determination comes after months of warnings by aid groups that Israel’s restrictions of food and other aid into Gaza were causing starvation among Palestinian civilians.

The IPC, a global body that monitors hunger crises, says 22 months of war in Gaza have left half a million people facing "starvation, destitution and death." Israel calls it "lies."

The White House has not commented on a report finding famine in Gaza. Analysts say that absent U.S. pressure, Israel is unlikely to change course.
