Weeks before the Israeli raid, a doctor described the crisis at Nasser hospital.

The Israeli military operation at Nasser Medical Complex on Thursday followed weeks of warnings from health officials about increasingly dire conditions inside the hospital. Doctors struggling with scarce supplies. Displaced people sleeping in corridors. Hunger gnawing as food grew scarce. Bombings and gunfire reverberating in the surrounding streets.

In a series of social media posts in late January, Ahmed Moghrabi, a surgeon at the hospital, described “two days of horror” as Israeli forces edged closer. Over two days, he said, the hospital, with just a dozen surgeons left, received more than 320 patients.
