The director of Al-Quds hospital in Gaza City, Bassam Mourad, has been speaking to the Reuters news agency - and he says he has received several warnings to evacuate the building.
“The first was through a phone call from the Palestinian Red Crescent which the Israeli army called to demand the evacuation of all patients and workers, as well as those residing in the hospital, to the south of Gaza.
"They mentioned that this area is going to be a military zone, that there will be clashes and the area will be dangerous and that we have to evacuate quickly,” he said.
He went on to say the number of displaced people residing in the hospital is somewhere between 12,000 to 14,000.
"The figure changes every day in addition to the hospital departments and the intensive care unit,” he says.
