At least 27 people have been killed in fierce clashes between Hamas fighters and a powerful clan in Gaza City, marking the deadliest internal fighting since Israel scaled back its major military operations in the territory.

Residents described scenes of chaos as families fled their homes under intense gunfire. Many of them have already been displaced multiple times during the months-long conflict, according to BBC’s Gaza correspondent.

The renewed violence comes as Israel awaits the release of the remaining hostages under the terms of a ceasefire agreement. Hamas has until 12:00 local time (10:00 BST) to hand over the captives.

Israeli Prime Minister Benjamin Netanyahu said “tomorrow is the beginning of a new path,” but cautioned that “very big security challenges” still lie ahead.

Under the deal, Israel is set to release 250 Palestinian prisoners and 1,700 detainees from Gaza, including nearly two dozen children, in exchange for the hostages.

Meanwhile, dozens of aid trucks have been seen entering the besieged enclave. Images show long lines of lorries queuing at the Rafah crossing with Egypt as relief operations resume amid fragile calm.

Elsewhere, former US President Donald Trump is preparing to join an international peace summit in Egypt on Monday, where world leaders are expected to discuss the next phase of the truce and the future governance of Gaza.

Drone footage from Gaza City shows extensive devastation, while UN officials have urged for a massive scale-up of humanitarian assistance. “We need to overwhelm Gaza with food,” said UN humanitarian chief Tom Fletcher.

Despite the ceasefire, uncertainty continues to loom over the region’s future. As BBC’s Middle East editor Jeremy Bowen noted, “no hard details have been worked out yet on the political future of Gaza.”
