At least 10 people have been killed in an Israeli attack that sparked a fire at a school sheltering displaced people in Gaza City, including one child who was burned to death in the blaze.

The Israeli military accused Palestinian militant groups of exploiting civilians and civil properties for military purposes, an allegation Hamas and other factions deny.

At least 50 Palestinians have been killed in Israeli strikes across the Gaza Strip on Thursday, health officials and first responders say. Nine people died in the morning when a missile hit a police station in the market area of Jabalia town, in the north, a hospital said.
