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.

Israel was keeping up its intense bombing campaign in the enclave, which has exacted a heavy price on civilians struggling to find safe places to shelter.
