broadcast of the BBC's Panorama his team is "seeking to bring closure to the case".

He added that directing civilians down a single route towards the site was "a very far cry from what was possible" under the UN-based system, which saw 400 distribution points scattered across the strip."This all looks designed to fail," he said of the new aid system.

According to the Hamas-run Gaza health ministry, some 31 people were killed by gunfire on Sunday.The GHF posted on its official Facebook page early on Sunday, telling civilians that SDS 1 would be open from 05:00 local time.However, just an hour later it posted again saying that the site was closed. By this time many Gazans had gathered at the Al-Alam roundabout as they waited to be granted access to the site, Mohammed Ghareeb, a journalist based in Rafah, told the BBC.

We have seen a limited amount of video that is claimed to relate to the shootings. In one video filmed on the route to the aid site, purportedly on Sunday, people lie on the ground and an explosion is heard which could be tank or artillery fire.An audio recording provided to the BBC by international staff at the UK-Med field hospital about 3km away from the site captured two apparent explosions and protracted gunfire for over five minutes.

Video footage posted at 06:08 showed dozens of people lying prone on sand, with automatic gunfire audible. BBC Verify could not definitively geolocate the footage.

Another clip reviewed by BBC Verify, which claimed to be from the aftermath of the incident, showed a number of bodies lying on a beach on Gaza's coast. As the video progresses, several of the bodies were covered by white bags. One of those lying on the beach appeared to be a young woman.The 33-year-old has adopted three former service animals in total, including her current companion Marco, who served with Durham Constabulary for two years.

"It is the most rewarding thing having a retired police dog," she said.During his police service, Marco, now aged five, tracked a vulnerable man in a wood during the middle of the night.

"The man was wearing camouflage clothing and was unconscious when located laying face down under a bush," Ms Meller said."Without Marco, there was no way they would have found him given how dark it was and his camo clothing."
