An Israeli strike in Gaza on Thursday killed a family of four including two children, Palestinian hospital and security sources said.

"The bodies of four members of the Ahmad family were recovered in pieces after an Israeli strike hit a house in the Beit Lahia Project area in the northern Gaza Strip," an official at Al-Shifa hospital in Gaza City said, identifying the children as aged 12 and eight.

The Israeli military, contacted by AFP, said it was checking.
