At least 20 people have been killed in an incident in Khan Younis, according to the Gaza Humanitarian Foundation (GHF), an Israel and US-backed organisation.
In a statement, it said 19 people were trampled and one was stabbed in a surge “driven by agitators in the crowd”.
“We have credible reason to believe that elements within the crowd – armed and affiliated with Hamas – deliberately fomented the unrest,” it said.
“For the first time since operations began, GHF personnel identified multiple firearms in the crowd, one of which was confiscated. An American worker was also threatened with a firearm by a member of the crowd during the incident.”

The Hamas-run Gaza health ministry claimed 21 Palestinians were killed, “including 15 who died of suffocation as a result of tear gas fired at the starving people and the subsequent stampede” at the GHF site.
The statement is unusual for the GHF, as the controversial group, which has been rejected by the United Nations and other aid groups, rarely acknowledges trouble at its distribution sites.
The GHF began distributing food packages in Gaza at the end of May, after Israel eased its 11-week blockade of aid into the coastal territory.

It has four distribution centres, three of which are in the southern Gaza Strip. The sites, kept off-limits to independent media, are guarded by private security contractors and located in zones where the Israeli military operates.
Palestinian witnesses say Israeli forces have repeatedly opened fire towards crowds of people going to receive aid.
The Israeli military says it has fired warning shots at people who have behaved in what it says is a suspicious manner. It says its forces operate near the aid sites to stop supplies from falling into the hands of militants.
After the deaths of hundreds of Palestinians trying to reach the aid hubs, the UN has called the GHF’s aid model “inherently unsafe” and a violation of humanitarian impartiality standards.
In response, a GHF spokesperson said: “The fact is the most deadly attacks on aid sites have been linked to UN convoys.”
The GHF says it has delivered more than 70 million meals to Gazans in five weeks and claims other humanitarian groups – which refuse to work with the GHF – had “nearly all of their aid looted” by Hamas or criminal gangs.

Since the GHF sites began operating, more than 875 people have been killed while receiving aid, both at GHF distribution points or elsewhere, according to the UN human rights office and the Hamas-run Gaza health ministry.
At least 674 of those being killed in the vicinity of aid distribution sites run by GHF.
