Witnesses and Gaza hospital officials say Israeli troops have killed at least 32 Palestinians near aid distribution hubs in the latest deadly violence involving people seeking desperately needed food.

At least 73 people were killed and around 150 people injured by Israeli gunfire in Gaza while seeking aid on Sunday, according to the Palestinian health ministry.

At least 94 Palestinians were killed Sunday by Israeli military fire across Gaza while trying to collect food aid, making it one of the deadliest days for humanitarian seekers in recent months.

The maximum number of casualties were reported from northern Gaza, where at least 67 people were killed while entering the region through the Zikim crossing with Israel, the report said citing the health ministry in the Palestinian territory and local hospitals.

Razan was one of at least four children to succumb in the last three days, the youngest just three months. Over the past 24 hours, 18 deaths have been recorded due to famine in Gaza, the health ministry says, reflecting a deepening crisis in the territory.

Israel says the seizure of territory in Gaza is aimed at pressuring Hamas to release hostages, but it is a major point of contention in ongoing cease-fire talks.
