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.

Mughrabi CAIRO (Reuters) -Israeli fire and airstrikes killed at least 35 Palestinians across the Gaza Strip, most of them near an aid distribution site operated by the U.S.-backed Gaza Humanitarian Foundation,

The group, which has been harshly criticized by the U.N. and other aid providers, said at least five people had died in an attack on one of its buses.
