Israeli planes and tanks pounded the eastern and northern outskirts of Gaza City overnight Saturday to Sunday, destroying buildings and homes, residents said, as Israeli leaders vowed to press on with a planned offensive on the city.

Israeli forces killed four aid seekers traveling on Sunday through a military zone south of Gaza City — an area regularly used by Palestinians trying to reach a food distribution point, a hospital and witnesses said.

Sixty-four people were killed in Israeli attacks across Gaza in the past 24 hours, the territory's Hamas-run health ministry said.
