Gaza's Health Ministry says Israeli troops have stormed one of the last hospitals operating in the territory's north and forced many of the staff and patients outside.

Staff at a hospital in northern Gaza say the building has been surrounded by Israeli forces and they are being ordered to evacuate along with all patients, after reports of a nearby airstrike that the local health ministry said killed about 50 people.

Israeli forces on Friday raided the Kamal Adwan Hospital, one of three medical facilities on the northern edge of Gaza, ordering dozens of patients and hundreds of others to evacuate and leaving part of the site on fire,
