Meanwhile, the U.N. Food Program said 77 trucks carrying aid were stopped by hungry people who took the food before the trucks were able to reach their destination.

The latest friction in negotiations comes as the fighting nears 20 months of war, and as desperation grows among hungry Palestinians and relatives of hostages in Gaza.

Officials said Hamas was seeking changes on guarantees for a permanent end to war. That has long been the core sticking point with Israel.

The BBC has hit back at White House press secretary Karoline Leavitt after she attacked its coverage of the war in Gaza. Leavitt accused the British public service broadcaster of spreading “misinformation” over the way it covered claims that Israel had killed Palestinians near an aid distribution center on Sunday.

The BBC has rejected incorrect White House criticism of its Gaza coverage, describing a claim that it had taken down a story as "completely wrong". At Tuesday's White House briefing President Trump's press secretary Karoline Leavitt accused the BBC of taking "the word of Hamas" when reporting on the number of people killed in a shooting near an aid distribution site on Sunday.
