The US- and Israel-backed Gaza Humanitarian Foundation (GHF) has said 20 people have been killed in what it called a "tragic incident" at one of its aid distribution centres in southern Gaza.
Nineteen were trampled to death and one was stabbed "amid a chaotic and dangerous surge" at the site in the Khan Younis area, a statement said. It added that it believed the surge was "driven by agitators in the crowd" who were affiliated to Hamas.
It was not immediately possible to verify the report.
However, officials at Nasser Hospital in Khan Younis earlier said that more than 10 people were killed and others injured due to "suffocation" after the GHF's private security contractors closed an aid site.
