An official of the health ministry in the Gaza Strip has said “at least 50 people” were killed when Israeli forces struck a United Nations school being used as a shelter for displaced people.

The strike on the UN-run Al-Fakhura school in the Jabalia refugee camp in the north of the Gaza Strip happened “at dawn”, the official told AFP.

Social media videos — which AFP was not able to verify — showed bodies covered in blood and dust on the floor of a building, where mattresses had been wedged under school tables.

The Israeli army did not immediately respond to a request for comment. The UN agency for Palestinian refugees (UNRWA) was also unable to offer an immediate reaction.
