At least 20 Palestinians have been killed in a crush at a food distribution site in southern Gaza run by the US-backed Gaza Humanitarian Foundation (GHF). It did not respond to questions about the use of pepper spray or teargas by its staff at the site near Khan Younis. Fifteen people died from suffocation after teargas was fired at the crowd, the Gaza health ministry said in a statement. Israeli forces have killed at least 800 Palestinians while they were trying to access food since the GHF began operations in late May. Many of them were trying to reach a GHF distribution site.
