Yemen Houthi Rebels Detain UN Staff in Raid on Sanaa Facility

The United Nations has demanded the swift release of 20 staff members detained by Yemen’s Houthi rebels after a raid on a UN compound in the capital, Sanaa. The detentions mark the latest escalation in the group’s ongoing crackdown on international agencies operating in rebel-held areas.

UN Confirms Detention of International and Yemeni Staff

Jean Alam, spokesperson for the UN resident coordinator in Yemen, confirmed that the detained staff included both Yemeni and international personnel. According to Alam, the incident occurred at a UN facility in the southwestern Hada district of Sanaa, where Houthi forces entered the compound and took control.

The detained group reportedly includes five Yemeni nationals and fifteen foreign staff members. Eleven others who were questioned during the operation were later released. Alam said the UN was in contact with the Houthis and other stakeholders “to resolve this serious situation as swiftly as possible, end the detention of all personnel, and restore full control over its facilities in Sanaa.”

Confiscation of UN Equipment Raises Concerns

A second UN official, speaking anonymously to the Associated Press due to the sensitivity of the issue, said that Houthi forces seized communications devices, including computers, servers, and mobile phones. The detained employees work for several UN agencies, including the World Food Programme (WFP), UNICEF, and the Office for the Coordination of Humanitarian Affairs (OCHA).

The seizure of communications and data equipment has heightened concerns about the security of sensitive humanitarian information. UN sources say the organization is assessing the potential impact on ongoing operations in northern Yemen, where humanitarian access is already restricted.

Pattern of Crackdown on International Agencies

The Houthis, officially known as Ansar Allah, have repeatedly targeted international organizations in territories under their control. The group has accused foreign staff of espionage — claims the UN and other agencies strongly deny. Over the past year, dozens of aid workers and local employees affiliated with global institutions have been detained in similar circumstances.

According to UN data, more than 50 UN staff members have been detained in Yemen since early 2024. The World Food Programme confirmed that one of its workers died in custody in the northern Saada province earlier this year, prompting global condemnation and renewed calls for accountability.

UN Operations Disrupted in Northern Yemen

Following a series of arrests in January, the UN suspended its operations in Saada, a Houthi stronghold, after eight of its employees were detained without explanation. The organization subsequently relocated its top humanitarian coordinator from Sanaa to the southern port city of Aden, where Yemen’s internationally recognized government is based.

Aid workers say the crackdown has made it increasingly difficult to deliver humanitarian assistance to millions of Yemenis facing food insecurity. Yemen remains one of the world’s worst humanitarian crises, with nearly 18 million people — more than half of the population — in need of assistance, according to UN reports.

Background: Houthis’ Control and the Yemen Conflict

The Houthi movement, backed by Iran, seized Sanaa in 2014, forcing Yemen’s internationally recognized government into exile. Since then, the country has been engulfed in a prolonged civil war, pitting the Houthis against a Saudi-led coalition supporting the government. Despite a relative lull in large-scale fighting, tensions remain high, particularly in areas where the Houthis exert control over international and local organizations.

The United Nations has maintained a presence in both Houthi and government-held territories, coordinating humanitarian relief, food distribution, and monitoring efforts to maintain fragile ceasefires. However, the latest detentions risk undermining international confidence and may further isolate the Houthis diplomatically.

Global and Regional Reactions

The United Nations and Western governments have condemned the detentions and called for the immediate release of all staff members. Diplomats familiar with the situation say quiet negotiations are ongoing through intermediaries in Oman and the UN’s Yemen office in Amman.

The European Union expressed “deep concern” over the reports, emphasizing that interference in humanitarian work violates international law. The U.S. State Department also issued a statement condemning the detentions, warning that continued hostility toward aid agencies “jeopardizes critical assistance for millions of Yemenis.”

Humanitarian Implications and Diplomatic Efforts

Analysts say the crackdown could worsen Yemen’s humanitarian crisis, which the UN describes as the world’s largest. “Every interruption to humanitarian access puts lives at risk,” said a regional expert at the International Crisis Group. “The Houthis’ actions could have severe consequences for aid delivery and international engagement.”

The UN Office for the Coordination of Humanitarian Affairs said it remains committed to dialogue with all parties. “We are working tirelessly to ensure the safety of our personnel and the continuation of life-saving operations,” a spokesperson said. “We urge all actors to respect the neutrality of humanitarian work.”

Outlook: Mounting Pressure on Houthi Leadership

As international pressure mounts, observers say the Houthis may face growing isolation. While the group has sought to present itself as a legitimate governing authority in northern Yemen, actions against UN staff risk deepening mistrust and complicating efforts toward a political resolution.

Peace efforts led by the UN Special Envoy for Yemen, Hans Grundberg, have struggled to gain momentum despite periodic ceasefire talks. The latest detentions are expected to further strain negotiations and hinder international mediation attempts aimed at ending a conflict now entering its second decade.
