The Gaza Humanitarian Foundation (GHF), the United States- and Israel-backed organisation established to supplant the aid work of the United Nations, has accused Hamas fighters of killing eight of its staff and wounding multiple others in an attack on a bus en route to a food distribution centre.

The Gaza Humanitarian Foundation said the attack, which the BBC could not independently verify, came after days of threats from Hamas.

Multiple aid workers were killed after a bus was attacked in Gaza on Wednesday night, according to a US-backed humanitarian aid organization which accused Hamas of carrying out the assault.
