Israeli forces bombarded houses in overnight attacks in the northern Gaza Strip, killing at least 15 people in one of the buildings in the town of Beit Lahiya, Palestinian medics said, according to Reuters.

Several others were wounded in the attack and others were missing after a house providing shelter to displaced people was struck, with rescue workers unable immediately to reach them, the Palestinian Civil Emergency Service said.

The three barely operational hospitals in the area were unable to cope with the number of wounded, they added.
