The UN says a school being used as a shelter has been damaged at the Jabalia Refugee Camp in Gaza, leaving 20 people reportedly dead.
Five people are understood to have also been injured at the camp.
Sky News has verified footage showing many injured people at the school, but has been unable to identify the cause. We are awaiting a response from the Israeli military.

The UN Relief and Works Agency (UNRWA) said it came “after two days of heavy bombardments in the area.”
“Earlier today, another shelter at Beach Refugee Camp was also damaged, with one child reportedly killed. Both locations are in the north of the Gaza Strip,” it added.
“Further south, two schools-turned-shelters in the Al Bureij Refugee Camp were hit. Two people were reportedly killed and 31 injured.”
The Israel Defence Forces (IDF) earlier justified attacks on buildings such as hospitals, schools and mosques in Gaza by claiming Hamas uses the sites for operational purposes.
IDF posted a video on X, formerly known as Twitter, on 27 October which asked: “Where are Hamas’s headquarters? Are they under a school? A university? A mosque? A hospital?
It then claims the answer is “all of the above”.
The footage of the damage caused to the UN school also emerged after 15 people were killed when Israel struck the Bureij refugee camp in central Gaza on Thursday.
Residents said dozens of people remained trapped under the rubble, with the blast creating a large crater and severely damaging buildings around the camp.
It came days after dozens were killed when Israel carried out a strike on a refugee camp in Jabalia, north of Gaza City.
Israel said it killed Ibrahim Biari, commander of Hamas’s Central Jabaliya Battalion, in the strike.
Biari was one of the leaders of the massacres in Israel on 7 October and had also been the “main leader” of Hamas’s combat operations since Israeli forces entered Gaza, IDF spokesman Rear Admiral Daniel Hagari said.
