An Israeli airstrike on a Gaza City school compound housing displaced Palestinian families killed around 100 people, the Gaza Civil Emergency Service said on Saturday, while Israel said the toll was inflated and 19 militants were among the dead.

Video from the site showed body parts scattered among rubble and more bodies being carried away and covered by blankets. Empty food tins lay in a puddle of blood, and burned mattresses and a child’s doll lay in the debris.

In another video, men prayed over a dozen body bags laid on the ground of the Tabeen school complex.

The Israeli strike drew condemnation from Arab states, Turkey, France, Britain and the European Union and an expression of deep concern from the U.S., which has been working with partners to prevent the 10-month-old Gaza conflict from escalating into a regional war.

Reiterating U.S. calls, Harris, the Democratic presidential candidate running for election in November, told reporters: “We need a hostage deal and a ceasefire.”

Gaza’s Civil Emergency Service, which has a credible record in stating casualty numbers, and the Hamas-run government media office said in separate statements that the complex had been attacked while its occupants were performing dawn prayers.

Tens of thousands of displaced Palestinians have sought shelter in Gaza’s schools, most of which have been closed since Israel’s war against Hamas began.

Around 350 families had been sheltering at the compound, Bassal said – some of the hundreds of thousands of Palestinians displaced by Israel’s onslaught on Gaza.

The upper floor housing families and the lower floor, used as a mosque, were both hit, he said.

The Israeli military said the death toll was inflated.

It added that no severe damage was caused to the compound, and provided aerial photos and videos which it said proved this.

The compound, and the mosque that was struck within it, served as an active Hamas and Islamic Jihad military facility,” Lieutenant Colonel Nadav Shoshani said on X, without providing evidence.

An Israeli army official said the part of the mosque that was struck was reserved for men.

Israel says Palestinian militants embed themselves among Gaza’s civilians, operating from within schools, hospitals and designated humanitarian zones – which Hamas and its allies deny.

Hamas said the strike was a horrific crime and a serious escalation. Izzat El-Reshiq of Hamas’ political office said the dead did not include a single combatant.

A separate strike on Saturday killed three Palestinians in Al-Nuseirat in central Gaza and another killed one person in nearby Deir Al-Balah, medics said.

Later in the day an Israeli strike killed three Palestinians in Rafah, near the border with Egypt, medics said.

Separately, the Israeli military said the head of general security in Hamas’ military wing, Walid Alsousi, had been killed in southern Gaza. There was no immediate Hamas comment.
