Fifteen Palestinians have died and more than 90 were injured after Israeli tank shells slammed into a crowded UN school sheltering Gaza war refugees, health officials and UN chiefs have said.

At least thirteen people have been killed in a tank shell attack on a United Nations school in Gaza, where hundreds of Palestinians had taken refuge from Israeli attacks.
