UN mourns 136 personnel killed in line of duty in 2025, 80 from Gaza
Synopsis
The UN’s 2025 memorial service revealed a grim record: 80 of the 136 personnel honoured died in Gaza — more than in any conflict or disaster in the organisation’s history. With multilateralism under pressure and UNRWA stretched thin, Guterres’ demand for accountability carries unusual urgency.

Secretary-General António Guterres declared that attacks on UN personnel violate international law and vowed the organisation would ‘never stop demanding accountability.’ Guterres warned that multilateralism itself is ‘under attack,’ framing the fallen as proof of the UN’s continued relevance.
The United Nations on Monday, 8 June 2025, held its annual memorial service at UN Headquarters in New York to honour 136 personnel who lost their lives in the line of duty over the past year — the largest single category of fatalities coming from the organisation's operations in Gaza. The tribute underscored what UN Secretary-General António Guterres described as an unprecedented toll on the world body's workforce.
Who Was Commemorated
Of the 136 personnel honoured, 97 were civilian staff and 39 were uniformed peacekeepers — comprising both military and police personnel. They represented 32 countries, reflecting the global reach of UN operations. “Diverse in background, but united in purpose,” Guterres said at the ceremony.
Gaza: The Deadliest Theatre in UN History
A striking 80 of the fallen had served in Gaza with the UN Relief and Works Agency for Palestine Refugees (UNRWA). Guterres stated plainly that more UN colleagues have been killed in Gaza than in any other conflict or disaster in the entire history of the organisation. “These tragedies weigh heavily on us all, and should be remembered by the entire world,” he said. The figure draws renewed attention to the conditions facing humanitarian workers in the territory amid ongoing hostilities.
A Call for Accountability
Guterres was unequivocal on the legal dimension: attacks on peacekeepers and humanitarian workers constitute a violation of international law, including international humanitarian law. “UN personnel must never be targeted,” he said, adding that the organisation would “never stop demanding accountability.” He reaffirmed the UN’s commitment to the security and safety of its staff everywhere.
Multilateralism Under Pressure
The Secretary-General used the occasion to address what he called a broader assault on the idea of collective action. “We live in a moment when multilateralism is under attack, when powerful forces would have us believe that the United Nations — that unity itself — is a pipedream,” Guterres said. He argued that the lives of those commemorated stand as a rebuttal to that view. “Courage, compassion, and commitment … These are the highest instincts of humankind,” he added.
What This Signals Going Forward
The record Gaza death toll is likely to intensify calls within the UN General Assembly and member states for stronger legal protections and enforcement mechanisms for humanitarian personnel in active conflict zones. With UNRWA’s operational capacity already under strain from funding pressures, the safety of its remaining field staff remains a critical concern heading into the second half of 2025.
Point of View
Surpassing every previous conflict in the organisation’s eight-decade history, demands more than a memorial speech. Guterres’ accountability demand rings hollow without a named enforcement mechanism; the UN has repeatedly condemned attacks on its staff in Gaza without consequence. The broader framing about multilateralism being ‘under attack’ is accurate, but the more immediate question is whether the organisation can protect its own people in the field — a test it is visibly failing.
