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.

Israel has called the United Nations' declaration of famine in parts of Gaza an "outright lie," but multiple U.N. bodies, more than 100 humanitarian groups, and several of Israel's own allies have warned for months that the war and Israel's restrictions of food into Gaza are causing starvation among civilians.

Hospital officials say Palestinians sheltering in tents or seeking scarce food aid were among at least 25 people killed by Israeli strikes in Gaza.
