Dozens of people have been killed after Israeli forces bombed the Al-Fakhoura school in Gaza on Saturday, Palestine's WAFA news agency reported.

The school, which is run by the United Nations agency for Palestinian refugees (UNRWA), is located in the Jabalia refugee camp in northern Gaza.

An official of the Hamas-run health ministry in the Gaza Strip said "at least 50 people" were killed in the bombing at the UN school, where displaced people have taken shelter. The strike happened at dawn, the official told AFP. 

There has been no response from Israel so far.
