Palestinians sheltering in tents or seeking scarce food aid were among at least 25 people killed by Israeli strikes and shootings Saturday in Gaza, according to local hospitals, as the world confronted an exceptional announcement that famine is now gripping Gaza’s largest city.

Despite outrage from its allies, the White House has not commented on a report that found famine in Gaza. Analysts say that without U.S. pressure, Israel’s war will not likely change course.
