United Nations agencies marked World Humanitarian Day on 19 August by warning that violence against health-care workers and facilities is worsening, and by urging governments and armed groups to safeguard humanitarian personnel. The World Health Organization said it has verified 821 attacks on health care so far in 2025, resulting in 1,121 deaths and 645 injuries to health workers and patients. Cumulatively, the agency has documented almost 2,500 such incidents worldwide over the past two years. Ukraine remains one of the deadliest theatres, with more than 2,500 attacks on medical facilities recorded since Russia’s full-scale invasion in February 2022, killing 215 people and injuring 810, according to WHO’s regional office. UNICEF, the UN Office for the Coordination of Humanitarian Affairs and Amnesty International echoed the call for stronger enforcement of international humanitarian law, saying repeated assaults on clinics, aid convoys and staff imperil millions of civilians who depend on lifesaving assistance. WHO highlighted its 70,000-strong European Emergency Medical Teams network—about 100 rapid-response units—as evidence that, despite the risks, humanitarian workers continue to deliver care in conflict zones. The agencies said political will, not new rules, is required to halt the attacks and end impunity.
