A United Nations team says 291 patients were left at Gaza’s largest hospital after Israeli troops had others evacuate. Those left include 32 babies in extremely critical condition, trauma patients with severely infected wounds and others with spinal injuries. The World Health Organization said Sunday that it was able to tour Shifa Hospital for an hour after about 2,500 displaced people, mobile patients and medical staff left the sprawling compound. Israel meanwhile signaled that it plans to expand its operations to southern Gaza, where it had told hundreds of thousands of Palestinians to seek refuge early in the war.
