AT least 17 people have been killed in an Israeli airstrike on a UN-run school in Gaza, according to reports.

More than 80 people were injured in Sunday’s attack on the Abu Oraiban school in the Nuseirat refugee camp, Al Jazeera reports.

It is reportedly the fifth attack on a school-turned-shelter in eight days.

The school was housing “thousands of displaced people”, said Mahmoud Basal, the Palestinian Civil Defence spokesman. He added that most of those killed were women and children.

The Israeli military said its air force “struck a number of terrorists who were operating in the area of UNRWA’s Abu Araban [Abu Oraiban] school building in Nuseirat”.

Al Jazeera reports that the Israeli military has repeatedly bombed buildings, schools and refugee camps in designated safe zones.

At least 90 people were reportedly killed after Israel attacked the al-Mawasi camp in southern Gaza, a designated “safe zone”.

The Israeli military has bombed 190 facilities run by UNRWA in Gaza, more than half of their total number.

The European Union, France and Germany have called for an investigation into the school strikes.
