DEIR AL-BALAH, GAZA STRIP -- An Israeli airstrike hit a school-turned-shelter in Gaza early Saturday, killing at least 80 people and wounding nearly 50 others, Palestinian health authorities said, in one of the deadliest attacks of the 10-month war between Israel and Hamas. A witness said it struck during prayers at a mosque in the building.
It was the latest of what the UN human rights office called “systematic attacks on schools” by Israel, with at least 21 since July 4 leaving hundreds dead, including women and children. “For many, schools are the last resort to find some shelter," it said after Saturday's attack.
The Israeli military acknowledged it targeted the Tabeen school in central Gaza City, saying it hit a Hamas command center in a mosque in its compound and killed 19 Hamas and Islamic Jihad fighters. Izzat al-Rishq, a top Hamas official, denied there were militants in the school.
Israel's military also disputed the toll, saying the “precise munitions” used “cannot cause the amount of damage that is being reported” by the Hamas-run government. It said the steps it took to limit the risk to civilians included "the use of a small warhead, aerial surveillance and intelligence information.”
Video from the scene showed walls blown out on the ground level of a large building. Concrete chunks and twisted metal lay on the blood-soaked floor, along with clothing, furniture and other debris. Bodies, some in bloodstained shrouds, were placed shoulder to shoulder in makeshift graves, making room for more.
Fadel Naeem, director of the al-Ahli hospital in Gaza City, told The Associated Press that the facility received 70 bodies along with the body parts of at least 10 others. Gaza's Health Ministry said another 47 people were wounded.
“We received some of the most serious injuries we encountered during the war,” he said, with many of the wounded having limbs amputated and some with severe burns.
The strike hit without warning before sunrise as people prayed, according to Abu Anas, a witness who worked to rescue people.
“There were people praying, there were people washing and there were people upstairs sleeping, including children, women and old people," he said, prayer beads in his hand. “The missile fell on them without warning. The first missile, and the second. We recovered them as body parts.”
Three missiles ripped through the two-story building — the first floor housing the mosque and the second the school — where about 6,000 displaced people were taking shelter, said Mahmoud Bassal, a spokesperson for the Civil Defense first responders, who operate under the Hamas-run government.
Many of the casualties were women and children, he said.
A camera operator working for the AP said the mosque and classrooms were in one building, with the prayer hall on the ground floor and the school above it. A missile appeared to have penetrated the floor of the classrooms to the mosque below and exploded, according to the operator.
The UN previously said that as of July 6, 477 out of 564 schools in Gaza had been directly hit or damaged in the war, adding that Israel has a duty under international law to provide safe shelter for the displaced.
“There’s no justification for these massacres," European Union foreign policy chief Josep Borrell said in a statement posted on X, referring to strikes on schools. U.K. Foreign Minister David Lammy said he was “appalled."
The U.S. said it was deeply concerned about reports of civilians killed. “Far too many civilians continue to be killed and wounded,” U.S. National Security Council spokesperson Sean Savett said in a statement.
Israel has blamed civilian deaths in Gaza on Hamas, saying the group endangers noncombatants by using schools and residential neighborhoods as bases for operations. The UN human rights office acknowledged that co-locating combatants with civilians is a violation of international humanitarian law, but that Israel must also comply with the law’s principles of precaution and proportionality.
The strike came as U.S., Qatari and Egyptian mediators renewed their push for Israel and Hamas to achieve a ceasefire agreement that could help calm soaring tensions in the region following the assassination of Hamas political leader Ismail Haniyeh in Tehran and a senior Hezbollah commander in Beirut.
Egypt, which borders Gaza, said the strike on the school showed that Israel had no intention of reaching a ceasefire deal. Neighboring Jordan condemned the attack as a “blatant violation” of international law. Qatar demanded an international investigation, calling it a “heinous crime” against civilians.
Late Friday, two separate airstrikes in central Gaza killed at least 13 people, including three children and seven women, hospital authorities said. An AP journalist counted the bodies at the al-Aqsa Martyrs hospital in the central city of Deir al-Balah.
One strike hit a house in the Nuseirat refugee camp, killing seven people, all but one of them women, hospital officials said. Another hit a house in Deir al-Balah, killing six, including a woman and her three children, the hospital said.
Israel’s campaign in Gaza has killed more than 39,790 Palestinians and wounded more than 92,000 others, according to the Health Ministry, which doesn't distinguish between combatants and civilians in its tally. The war was triggered by Hamas’ Oct. 7 attack in which militants from Gaza stormed into southern Israel, killing around 1,200 people and abducting 250 others.
More than 1.9 million of Gaza’s prewar population of 2.3 million have been driven from their homes, fleeing repeatedly across the territory to escape offensives. Most are now crowded into tent camps in an area of about 50 square kilometres (19 square miles) on the Gaza coast with few basic services or supplies.
In the occupied West Bank, dozens of people gathered in Ramallah to protest the latest Israeli strike on a school.
“The message that must be sent to the world, a numb world, a world that is not moving, is ‘how long will the war continue?’” asked one, Muin Barghouti.
