Israel's army says it hit a terrorist command center in Gaza. The U.N. says it was the deadliest strike for its staff during the war.

Gaza's civil defence agency said that an overnight Israeli air strike hit a house in Gaza City where displaced Palestinians had taken refuge, killing 11 people, including women and children.

Gaza civil defence agency spokesman Mahmoud Bassal said the bodies of '11 martyrs' had been recovered, adding that these included four children and three women.
