Gaza health officials and the ambulance service say at least 25 people were killed by Israeli airstrikes and gunshots overnight as ceasefire talks appear to have stalled and Palestinians in Gaza are facing famine.

At least 73 Palestinians were killed on Sunday while trying to get food at distribution sites, officials said.

At least 93 Palestinians queuing for food aid have been killed, according to officials in the Hamas-run Gaza Strip, most of them reportedly shot by Israeli forces at the Zikim crossing.
