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.

Internet and landline services were also cut off in the enclave after key telecommunications infrastructure was damaged, according to a Palestinian ministry.

The GHF, which began distributing food aid barely two weeks ago from sites in the southern and central Gaza Strip, said the team of about two dozen staff were attacked about 10 p.m. local time while traveling to a distribution center west of Khan Younis.
