At least nine people were killed in another Israeli airstrike on a UN-run school sheltering displaced civilians west of Gaza City on Sunday, a medical source said.
Twenty other people were injured in the attack that targeted Asma School, run by the UN agency for Palestinian refugees (UNRWA) in the Shati refugee camp, the source added.
The attack was the second to have targeted the same school within days.
An Israeli airstrike hit the school on Oct. 19, leaving at least 10 people dead and injuring others.
Israel has systematically targeted civilian facilities, including schools, hospitals, and places of worship, amid its ongoing offensive on the Gaza Strip.
Under the rules of war, targeting such civilian facilities can constitute a war crime.
The Israeli army has continued a devastating offensive on the Gaza Strip since a Hamas attack last year, despite a UN Security Council resolution demanding an immediate cease-fire.
Nearly 43,000 people have since been killed, mostly women and children, and over 100,000 others injured, according to local health authorities.
The Israeli onslaught has displaced almost the territory's entire population amid an ongoing blockade that has led to severe shortages of food, clean water, and medicine.
Israel also faces a genocide case at the International Court of Justice for its actions in Gaza.
