The UN agency for Palestine refugees, UNRWA, maintained that Israeli forces hit the school in Al Bureij, Middle Gaza, at around 6pm on Tuesday and again at 10.20pm.
âThe school sustained severe damage and a fire broke out in the shelter, making it difficult to evacuate the casualties. Residents had to open a hole in the wall to evacuate the dead and wounded,â UNRWA told UN News.
Since the start of the war between Hamas and Israel on 7 October 2023, more than 400 schools have received a direct hit, according to satellite imagery analyzed by the UN.
Deadly aftermath
Footage from the scene provided by the UN agency showed walls and floors blown out in the main school building.
In the courtyard, hundreds of people can be seen standing amid crumpled metal sheeting on the morning after the attack, with rubble and wooden planks strewn around where their shelters had been standing just hours earlier.
âOur colleagues are reporting that surviving parents and children are trying to salvage their belongings among the blood and body parts of their relatives and neighbours,â UNRWA said.
The agency noted that fatalities included women and children, while search and rescue operations are ongoing for several people still missing.
Many of those living at the school when it was hit have been displaced âcountless timesâ by the war, which began on 7 October 2023, following Hamas-led terror attacks on Israel, UNRWA stressed.
The attack also sparked a fire in an adjacent school where more tents and temporary shelters were burned and damaged.
Education destroyed
According to the UN Satellite Service, UNOSAT, 95.4 per cent of schools in Gaza have sustained damage since the start of the war.
Of the enclaveâs 564 schools, 501 will either need full reconstruction or major rehabilitation work to be functional again.
âThere is no humanity left in Gaza, and no humanity left as the world continues to watch day after day as families are bombed, burned alive and starved,â UNRWA said after the latest attack.
Failed strategy wonât work: TĂźrk
In a related development, the UN human rights chief Volker TĂźrk on Wednesday condemned Israelâs reported plans to forcibly transfer Gazaâs population to a small area in the south of the Strip.
The move fuels concern that Israelâs intention is to make life for Palestinians âincreasingly incompatible with their continued existence in Gazaâ, he said in a statement.

âThere is no reason to believe that doubling down on military strategies, which, for a year and eight months, have not led to a durable resolution, including the release of all hostages, will now succeed,â insisted the UN High Commissioner for Human Rights.
Expanding the offensive on Gaza âwill almost certainly cause further mass displacement, more deaths and injuries of innocent civilians, and the destruction of Gazaâs little remaining infrastructureâ, he continued.
Rights experts warn of irreversible consequences
Escalating atrocities in Gaza mark a critical moral turning point and demand urgent international action, UN-appointed independent human rights experts said in a statement.
âWhile States debate terminology â is it or is it not genocide? â Israel continues its relentless destruction of life in Gaza,â they warned, citing attacks by land, air and sea, and a soaring civilian death toll.
âNo one is spared â not children, persons with disabilities, nursing mothers, journalists, health professionals, aid workers, or hostages,â they said, noting that on 18 March alone, 600 Palestinians were reportedly killed, 400 of them children. The independent experts are appointed by the Human Rights Council, are not UN staff members and receive no salary for their work.

Occupied West Bank update
In the occupied West Bank, meanwhile, UN aid teams warned of worsening conditions for Palestinian communities because of âviolence by Israeli forces and settlersâ.
The alert comes after Israeli forces on Monday demolished more than 30 structures in Khallet Athaba, a hamlet in Hebron governorate, displacing nearly a dozen families â or around 50 people.
âThis constitutes most of the structures in the community and marks the third and largest demolition there since February,â said UN aid coordination office, OCHA. It noted that the area is designated by Israel as a military training zone.
In addition, Israeli forces also began demolishing six homes in Nur Shams refugee camp in Tulkarm on Monday, impacting 17 families. They are among more than 100 buildings slated for demolition, following an Israeli notice issued at the start of the month.
Forcible transfer fears
OCHA described how dozens of families in the camp were given little time on Monday to collect their belongings before their homes were demolished.
The agency highlighted the âstrong pushâ to uproot Palestinians living in the area âonce again raising concerns about the risks of forcible transfer of the populationâ.
Under international law, Israel as the occupying power, has the responsibility to protect Palestinians in the West Bank and ensure their safety and dignity, OCHA insisted.
Humanitarian partners are mobilizing assistance, but urgent international engagement is needed to stop these coercive measures and protect vulnerable communities, the UN aid office said.
