Hospitals in Gaza reported the killing of more than a dozen people, eight of them food-seekers, by Israeli fire on Saturday as Palestinians endured severe risks in their search for food amid airdrops and restrictions on overland aid delivery.

Israel’s nearly 22-month military offensive against Hamas has shattered security in the territory of some 2 million Palestinians and made it nearly impossible to safely deliver food to starving people.

Steve Witkoff went to the Palestinian enclave amid growing pressure on Israel to ease a deepening hunger crisis there. Hamas derided the visit as a “propaganda show.”
