Yemen’s Houthis Detain 73 UN Staff and Aid Workers as Humanitarian Crisis Deepens
Sanaa, Yemen — The de facto Houthi authorities have held 73 United Nations staff members and dozens of humanitarian workers in arbitrary detention for over two years, according to a joint statement from the Cairo Institute for Human Rights Studies (CIHRS), Human Rights Watch, and Amnesty International. The detentions, which began with a series of raids in May 2024, have escalated as Yemen’s humanitarian crisis reaches catastrophic levels, with the World Food Programme (WFP) warning that four districts under Houthi control face famine conditions by mid-2026.
The latest victim, a WFP aid worker who died in Houthi custody on February 11, 2025, underscores the dire conditions inside detention centers. Since the initial arrests, only seven detainees have been released, while the Houthis have continued to target staff from international and Yemeni civil society organizations, accusing them of “espionage” and “conspiring” against the country. The crackdown has paralyzed critical aid operations, with families reporting that detainees—including those with serious medical conditions—have been denied legal representation, forced to make coerced video confessions, and subjected to torture.
Why the Detentions Matter
The Houthis’ campaign against aid workers is part of a broader strategy to silence dissent and control information in northern Yemen, where they maintain de facto authority. Since 2015, the group has used spying charges to arrest political opponents, journalists, and activists, according to Amnesty International. The detentions of UN staff—including four Yemeni employees of the Office of the UN High Commissioner for Human Rights (OHCHR) and UNESCO, arrested in 2021 and 2023—highlight the Houthis’ disregard for international law. The death of a Save the Children security director in October 2023, while held incommunicado, further exposed the risks faced by humanitarian workers.
Human Rights Watch and Amnesty International have documented systematic torture and ill-treatment in Houthi detention centers, including the use of electric shocks, solitary confinement, and forced confessions. Despite some detainees receiving medical care, many—including those with chronic illnesses—have been left without treatment. Legal access remains blocked: no detainee has been allowed a lawyer, despite three UN employees’ cases being transferred to the Specialized Criminal Court in December 2025.
How the Crisis Is Worsening
The detentions have directly hindered life-saving aid in Yemen, where 24.4 million people—nearly 80% of the population—require humanitarian assistance, according to the UN. The WFP and the UN Food and Agricultural Organization (FAO) warned in January 2026 that acute food insecurity will deteriorate further, with pockets of Yemen facing “catastrophe” levels of hunger—a classification reserved for the most extreme famine conditions. The Houthis’ restrictions on aid workers have disrupted grain deliveries, medical supplies, and nutrition programs, exacerbating malnutrition rates already at crisis levels.
Funding cuts from donor states, particularly the U.S. suspension of aid in 2024, have compounded the problem. Despite reduced international support, local and international NGOs continue to operate in Houthi-controlled areas, but their ability to do so is increasingly constrained by arrests and threats. The Houthis’ media campaign—accusing aid organizations of “espionage” and “foreign interference”—has created a climate of fear, with workers reporting harassment and surveillance even before detentions occur.
What Happens Next?
International pressure to secure the detainees’ release has so far yielded limited results. The UN and humanitarian organizations have called for a unified response, but diplomatic efforts remain fragmented. The U.S. and Saudi Arabia, both engaged in indirect negotiations with the Houthis, have not publicly condemned the detentions in a coordinated manner. Meanwhile, the Houthis have rejected demands for unconditional releases, insisting that charges against detainees—including allegations of working with “foreign entities”—must be addressed first.
Families of the detained workers have reported no progress in securing their loved ones’ freedom. In some cases, authorities have denied access to families, leaving them without updates on their relatives’ conditions. The death of the WFP aid worker in February 2025 serves as a grim reminder of the immediate risks faced by those still held. With no end to the detentions in sight, the humanitarian crisis in Yemen shows no signs of abating.
The Houthis’ actions have isolated them further on the global stage, with even traditionally neutral actors like the UN expressing growing frustration. Yet without a clear diplomatic strategy to compel their compliance, the fate of the detained aid workers—and the millions of Yemenis who depend on their work—remains uncertain.
