Ten Palestinians were killed by Israeli tank fire in Gaza on Friday, local health authorities said, as a U.S.- and Israeli-backed group handing out aid in the enclave said all its distribution sites were closed until further notice.

The Gaza Humanitarian Foundation said it was working to improve operations, a day after health workers said at least 27 Palestinians were killed near a distribution center.

The U.S backed-Gaza Humanitarian Foundation said on Friday that all its aid distribution sites in the enclave were closed and a reopening date would be announced later, urging residents to stay away from these sites "for their safety".

The bodies of two Israeli-American hostages abducted by Hamas on October 7 were recovered from southern Gaza during a military operation, according to a statement from Israeli military and the Shin Bet security agency.

Israeli Americans Judi Weinstein Haggai, 70, and her husband Gadi, 72, were killed during the 7 October 2023 attacks.

Activist Greta Thunberg said in a video released on Wednesday (June 4) the story the world needs to focus on is what she called Israel's "siege and oppression" of Gaza, rather than her voyage with a humanitarian group to deliver aid to the enclave.
