Fighting between Israeli forces and Palestinian militants outside Gaza's largest hospital has prompted thousands of people to flee from the sprawling medical facility, but hundreds of patients and others displaced by the war remained inside, health officials said Monday. U.S. President Joe Biden said Shifa hospital “ must be protected ” and called for “less intrusive action” by Israeli forces. Gaza City, the largest urban area in the territory, is the focus of Israel’s campaign to crush Hamas following the militant group's deadly Oct. 7 incursion into southern Israel that set off the war.
