Agencies Gaza At least 31 Palestinians have killed across the Gaza Strip, 24 of them just within the past 12 hours.

Ten died in a western Gaza neighbourhood when the Israeli military dropped a bomb, partially destroying a school which had been turned into a shelter for thousands of displaced families.

At least three bombs were then dropped on the school as rescuers and volunteers inside the facility were trying to help people from under the rubble.

Those three bombs destroyed the facility completely. We don’t know exactly how many people have been killed in that attack yet.

This is the tactic that the Israeli military has widely used in the past. The military drops a bomb that partially destroys facilities, namely evacuation centres, killing a number of people, and then within a few minutes, it drops other bombs.

At least 10 people were killed when two Israeli strikes targeted a school sheltering displaced Palestinians in Sheikh Radwan neighbourhood.

In footage obtained and verified by Al Jazeera, victims of the Israeli attack on Hamama School are seen arriving at al-Ahli Hospital.

Among the seriously wounded were children, some of whom appeared to be unconscious, as medical staff desperately tried to treat them.

The scenes at the hospital were chaotic, with some of the wounded lying on the floors as grieving Palestinians lined the corridors.

According to the testimony of one of the wounded, the strikes were carried out without warning. Below is footage from the Israeli strike on the school:
