RAFAH, Gaza Strip (AP) — Israeli forces are battling Palestinian militants near the main hospital in Gaza’s second-largest city, Khan Younis. Medics said Wednesday that hundreds of patients and thousands of displaced people are unable to leave because of the fighting. Nasser Hospital is one of only two hospitals in southern Gaza that can still treat critically ill patients. The Israeli military says it has completed its encirclement of Khan Younis as part of its three-month-old offensive against Hamas. It has ordered residents to leave a swath of downtown Khan Younis that includes Nasser and two smaller hospitals. The United Nations humanitarian office says the area is home to 88,000 Palestinians and was hosting another 425,000 displaced by fighting elsewhere.
