An Israeli airstrike on Tuesday destroyed a prison in Gaza’s Shati refugee camp, reportedly killing dozens of prisoners and policemen.

The attack occurred amid a new wave of Israeli airstrikes across Gaza, which have killed hundreds of people, according to local health officials.

Footage from the scene showed collapsed buildings and people trying to reach bodies buried under the rubble.

The strike shattered a ceasefire that had held since January, reigniting concerns about the ongoing 17-month war.

Relatives of hostages still being held in Gaza and their supporters slammed Israel’s decision to carry out airstrikes in the enclave.
