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.

The war began when Hamas-led terrorists killed around 1,200 people, mostly civilians, in the Oct. 7 attack and abducted 251 hostages. More than half the captives have been released in ceasefires or other deals. Israeli forces have rescued eight and recovered the remains of dozens more.
