Residents say military gave them 20 minutes to evacuate 15-storey building before attacking, with casualties unclear

An Israeli strike has destroyed a high-rise building in Gaza City – the second in as many days – as the military demanded residents move to a so-called humanitarian zone in the south of the territory and slaughtered at least another 56 Palestinians, including aid-seekers.

Israel on Saturday issued evacuation warnings for two high-rises in Gaza City and surrounding tents. Avichay Adraee, a military spokesperson, claimed without providing evidence that the buildings were targets because Hamas had infrastructure inside or near them. Soon after, Adraee said that the military had struck one of the buildings.

Hamas said the allegations were “baseless lies” and that the high-rises were residential towers.

Residents of Sousi Tower, a prominent 15-story building, told the Associated Press that the Israeli army gave them about 20 minutes to grab their belongings and flee before warplanes razed the building to the ground.
