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.

Hospital officials in Gaza say Israeli strikes and gunfire have killed at least 33 Palestinians sheltering in tents or seeking scarce food aid.

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