Twelve people have drowned trying to reach aid dropped by plane off a Gaza beach, Palestinian health authorities have said, amid growing fears of famine nearly six months into Israel’s military campaign.

Video of the airdrop obtained by Reuters showed crowds of people running towards the beach, in Beit Lahia in north Gaza, as crates with parachutes floated down, then people standing deep in water and bodies being pulled onto the sand.

The video showed the lifeless body of a bearded young man being hauled onto the beach, the eyes open but unmoving, and another man trying to revive him with chest compressions as somebody said, “It’s over.”

“He swam to get food for his children and he was martyred,” said a man standing on the beach who did not give his name.

“They should deliver aid through the [overland] crossings. Why are they doing this to us?”
