Graphic video footage released by Gaza’s Civil Defense of what they say was the aftermath of an Israeli attack on a United Nations school shows a scene of destruction, with several women and children among the injured.

Mahmoud Basal, a spokesman for the Civil Defense, said on Monday that 10 people were killed and 30 injured in the attack on the school in the Jabalya refugee camp, where displaced Palestinians are sheltering amid Israel’s renewed military offensive in northern Gaza.

CNN has not been able to independently verify the location of the video and has asked the Israeli military for comment.

Videos from Basal show a chaotic scene with several women and children seriously injured and bleeding profusely.

In one of the videos, a woman’s voice can be heard shouting, “I have nothing to stop the bleeding,” as she runs from one victim to another.

The woman appears to film the videos herself. At one point she stops at a staircase, opens a doctor’s bag and tries to help with what little she has. Children and a man are seen bleeding over the stairs. A boy shouts hysterically: ‘Daddy! Dad!”

The woman runs to another location and explosions are heard in the background. She then sees an older man, hunched over and motionless. The woman shouts: ‘Uncle Abu Mohammed, no, no. Uncle.”

More videos, which appear to have been filmed by the same woman, show the bodies of at least two men on the ground. Seeing them, the woman shouts:

In another scene you see a woman, a boy and a girl sitting and lying on the floor. The boy and girl are both seriously injured and visibly traumatized, and the girl’s foot is partially severed at the ankle.

The head of the UN Palestinian refugee agency has accused Israel of preventing aid from reaching northern Gaza.
