At least 16 Palestinians have been killed in an Israeli attack on a United Nations-run school sheltering displaced people in the Gaza Strip, the Gaza Government Media Office said, as Israel continues to pound the besieged coastal territory.

Videos taken at the scene of the attack on the UNRWA school-turned-shelter in Nuseirat showed twisted metal at the collapsed building. A young boy could be seen sifting through pools of blood on the ground.

Footage shot at Al-Aqsa Martyrs Hospital in nearby Deir el-Balah and verified by Al Jazeera’s Sanad agency also showed children and young people being rushed from ambulances.

They included a girl with a bandaged arm, another with a bloodied face and a boy bandage across his head. Emergency workers also tried to cover two bodies as they were quickly brought into the medical complex.
