An official of the Hamas-run health ministry in the Gaza Strip said more than 80 people were killed on Saturday 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. 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.
