UN doctors were granted access to the Nasser Medical Complex on Sunday, two days after Israeli troops raided the facility after reportedly receiving intelligence that hostages were being held there.
Video filmed inside shows medical workers evacuating patients by torchlight and describing damage to the facilities. One UN doctor describes the scene as a “death zone”.
Gaza’s Hamas-run health ministry on Monday said 14 patients had been transferred to other hospitals.
The Israeli military says no-one died as a result of its actions and that its troops have been told to keep the hospital running.
