Witkoff and the U.S. ambassador to Israel, Mike Huckabee, visited an aid site in Gaza run by the controversial Israel and U.S.-backed Gaza Humanitarian Foundation (GHF) on Friday, as the United Nations said that over 1,373 Palestinians have been killed while seeking food since the end of May, including 859 at GHF sites.

Hamas said on Sunday it was prepared to co-ordinate with the Red Cross to deliver aid to hostages it holds in Gaza if Israel meets certain conditions, after a video it released showing an emaciated captive drew sharp criticism from Western powers.
