The overnight strike occurred in Muwasi, a sprawl of crowded tent camps along the Gaza coast that Israel designated as a humanitarian zone for hundreds of thousands of civilians to seek shelter from the nearly year-old Israel-Hamas war.

Associated Press footage shows three large craters at the scene. First responders dug through the sand and rubble with garden tools and their bare hands, using mobile phone flashlights until the sun came up. They pulled body parts from the sand, including what appeared to be a human leg.
