Israeli forces have entered the al-Shifa Hospital complex in Gaza City, which is housing hundreds of patients and thousands of displaced people despite a days-long siege. Heavy combat has raged around hospitals in Gaza for several days, halting ambulances and further stressing a beleaguered health-care system that’s rapidly running out of fuel and other resources. Dozens of patients in al-Shifa Hospital have died in recent days, Gaza Health Ministry officials said, and bodies have piled up in morgues that have run out of power.
