CAIRO: Israeli fire and airstrikes killed at least 12 Palestinians on Sunday across the enclave, local health authorities said, at least five of them near two aid sites operated by the U.S.-backed Gaza Humanitarian Foundation (GHF).

Medics at Al-Awda Hospital in the central Gaza Strip said at least three people were killed and dozens wounded by Israeli fire as they tried to approach a GHF site near the Netzarim corridor. Two others were killed en route to another aid site in Rafah in the south.

An airstrike killed seven other people in Beit Lahiya town north of the enclave, medics said. There was no immediate comment from the Israeli military.

The GHF began distributing food packages in Gaza at the end of May after Israel partially lifted a near three-month total blockade. Scores of Palestinians have been killed in near-daily mass shootings trying to reach the food.

The United Nations rejects the Israeli-backed new distribution system as inadequate, dangerous, and a violation of humanitarian impartiality principles.
