An official of the health ministry in the Gaza Strip has said more than 80 people were killed in double Israeli strikes on the Jabalia refugee camp.

“At least 50 people” were killed in an Israeli strike at dawn on the UN-run Al-Fakhura school in the camp, which had been converted into a shelter for displaced Palestinians, the official told AFP.

A separate strike on another building in the camp on Saturday killed 32 people from the same family, 19 of them children, the health ministry official said.

Jabalia is the biggest refugee camp in Gaza, where some 1.6 million have been displaced by more than six weeks of fighting between Israel and Hamas.

The Israeli army did not immediately respond to requests for comment on the two strikes. The UN agency for Palestinian refugees (UNRWA) was also unable to offer an immediate reaction.
