Israeli forces killed four aid seekers traveling on Sunday through a military zone south of Gaza City — an area regularly used by Palestinians trying to reach a food distribution point, a hospital and witnesses said.

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.

Netanyahu on Thursday said he had instructed officials “to begin immediate negotiations” to release hostages and end the war on Israel’s terms.
