The following statement by UN Secretary-General António Guterres was issued today:

I strongly condemn the arbitrary detention by the Houthi de facto authorities on 23 January of seven additional United Nations personnel in areas under their control.

I demand the immediate and unconditional release of those detained on Thursday, as well as the personnel from the United Nations, international and national non-governmental organizations, civil society and diplomatic missions arbitrarily detained since June 2024 and those held since 2021 and 2023. Their continued arbitrary detention is unacceptable.

The personnel of the UN and its partners must not be targeted, arrested or detained while carrying out their duties for the UN for the benefit of the people they serve. The safety and security of UN personnel and property must be guaranteed.

The continued targeting of UN personnel and its partners negatively impacts our ability to assist millions of people in need in Yemen. The Houthis must deliver on their previous commitments and act in the best interests of the Yemeni people and the overall efforts to achieve peace in Yemen.

The United Nations will continue to work through all possible channels to secure the safe and immediate release of those arbitrarily detained. I welcome the collective support of international partners, non-governmental organizations and all those working to support the people of Yemen in these efforts.

The UN has suspended all official movements by its teams into and out of Houthi-held areas of Yemen, after more UN staffers were detained on Thursday.

The de facto rulers of much of the country, including the capital Sana’a, released the crew of a merchant ship who had been held for more than a year, earlier this week.

The move raised hopes that more than 60 staff from the UN, international organizations and diplomatic missions already being held by the Houthis over the past year, might be released.

Friday’s safety measure announced by Julien Harneis, UN Resident and Humanitarian Coordinator for Yemen, comes as the organization faces mounting security challenges in its operations in the region.

The Houthis and the internationally-recognized Government have been fighting for control of the country in what has become a wider regional proxy war, for over a decade.

Security measure

“Yesterday, the de facto authorities in Sana’a detained additional UN personnel working in areas under their control,” Mr. Harneis said.

“To ensure the security and safety of all its staff, the United Nations has suspended all official movements into and within areas under the de facto authorities’ control…this measure will remain in place until further notice.”

Deputy Spokesperson Farhan Haq elaborated on the response later on Friday, highlighting the UN’s ongoing efforts: “Our officials in Yemen are actively engaging with senior representatives of the de facto authorities, demanding the immediate and unconditional release of all UN personnel and partners.”

The detentions mark a troubling escalation for humanitarian operations in Yemen, where access and security remain critical concerns.

The UN continues to emphasise the importance of upholding the safety and neutrality of its personnel to ensure lifesaving aid reaches those in need.
