Mohammed Ibrahim Al-Shami, an employee of the Office of the United Nations High Commissioner for Human Rights (OHCHR), died on Saturday, October 31, 2026, inside a detention facility operated by the Houthi militia in Sana’a, following nearly 29 months of arbitrary detention and enforced disappearance.
Al-Shami’s family received his body after his death, just two weeks after his relatives and a group of Yemeni intellectuals issued urgent appeals on October 17, calling for disclosure of his whereabouts and demanding access to him amid reports that his health had seriously deteriorated. All contact with Al-Shami had been cut off since June 6, 2024, when Houthi Security and Intelligence Service personnel abducted him and subsequently denied him family visits and access to legal counsel.
His death places the United Nations system before a fundamental test of its ability to protect its locally recruited personnel. It also exposes how the detention of employees of international organizations in Sana’a has gone beyond arbitrary imprisonment, amounting to a form of indirect execution through torture and the deliberate denial of medical care.
According to official United Nations statistics released on October 14, 2026, a total of 72 personnel from UN agencies, international and local organizations, and diplomatic missions were being detained by the Houthi militia. Following the recent release of detainee Sami Al-Kulabi and the death of Mohammed Al-Shami in custody today, 70 UN personnel and humanitarian workers remain in Houthi detention facilities, facing an uncertain fate.
This figure has accumulated through a series of coordinated raids launched by the Houthi Security and Intelligence Service in May and June 2024 across Sana’a, Hajjah, Al Hudaydah, and Saada. Subsequent waves of arrests continued throughout 2025 and 2026, targeting employees of the Office of the United Nations High Commissioner for Human Rights (OHCHR), the World Food Programme (WFP), the United Nations Office for the Coordination of Humanitarian Affairs (OCHA), the United Nations Children’s Fund (UNICEF), the United Nations Educational, Scientific and Cultural Organization (UNESCO), the Office of the United Nations High Commissioner for Refugees (UNHCR), the United Nations Development Programme (UNDP), and the Office of the Special Envoy of the Secretary-General for Yemen (OSESGY).
These arrests coincided with raids on UN premises in Sana’a and the confiscation of UN property and documents, in an effort to prevent the transfer of the agencies’ financial and administrative operations to the interim capital, Aden.
Inside detention facilities operated by the Houthi Security and Intelligence Service, under the direct supervision of the militia’s leadership, the 70 remaining detainees face a systematic pattern of repression. This begins with enforced disappearance and the complete denial of their detention, effectively placing them beyond any form of legal oversight. It is followed by harsh interrogations in dark solitary confinement cells, where beatings, simulated drowning, and sleep deprivation are reportedly used to extract coerced, video-recorded confessions that are subsequently broadcast through the group’s media outlets.
These practices are compounded by the denial of essential medication and routine medical examinations to detainees suffering from serious and chronic illnesses. Documented information held by the American Center for Justice (ACJ) as of early October 2026 confirms that among those detained are individuals with diabetes who have been denied necessary medical care, a detainee at risk of losing his sight due to glaucoma, and another suffering from stomach cancer who is undergoing chemotherapy while in custody.
Mohammed Al-Shami’s death is not an isolated incident in the record of deaths inside Houthi detention facilities. On February 11, 2025, Ahmed Baalawi, an employee of the World Food Programme, died inside a Houthi detention facility in Saada Governorate, less than three weeks after being abducted alongside six of his colleagues on January 23 of the same year.
Hisham Al-Hakimi, Security and Safety Manager at Save the Children, also died in October 2023 inside a prison operated by the Houthi Security and Intelligence Service in Sana’a, approximately 50 days after his enforced disappearance, without any charges having been brought against him. In another case, Abdullah Shamsan Al-Akhali, an information technology engineer with the Office of the United Nations High Commissioner for Refugees (UNHCR), died in Sana’a in October 2025 following a heart attack reportedly caused by intensive Houthi intimidation campaigns and security harassment targeting UNHCR personnel.
Beyond deaths occurring directly inside detention facilities, Yemeni human rights organizations have documented the deaths of at least 98 abductees and civilian detainees in the days or weeks following their release over the past eight years. These include documented cases in February 2025 in which individuals died just 11 days after being released.
Such delayed deaths have been attributed to the severe deterioration of detainees’ health while in custody, including kidney failure, liver cirrhosis, and blood clots resulting from torture and starvation. According to human rights organizations, some detainees are released only when they are on the verge of death, allowing those responsible to evade criminal accountability for deaths that might otherwise have occurred inside detention facilities.
There are also serious suspicions that some detainees have been injected with slow-acting toxic substances or administered unidentified drugs under the pretext of medical treatment shortly before their release, resulting in the subsequent collapse of their vital organs.
When the Houthi militia fails to secure immediate political concessions through its detention of UN personnel, it refers their cases to what it calls the “Specialized Public Prosecution and Specialized Criminal Court” in Sana’a, using judicial proceedings to provide a legal façade for their elimination.
After the Houthi prosecution announced in November 2025 that it had begun investigations into 17 detainees employed by various organizations, it referred at least eight UN and civil society workers for direct criminal trial in early October 2026. They face charges of “espionage on behalf of foreign countries” and “undermining national security,” both of which carry the death penalty.
These proceedings are conducted behind closed doors, with detainees denied the right to appoint independent legal counsel or examine their case files. The indictments, meanwhile, are based entirely on confessions allegedly extracted under coercion and used to criminalize legitimate humanitarian and human rights activities, including monitoring and documenting violations and assessing humanitarian needs.
In assessing the legal implications of these violations, international humanitarian law experts consulted by the American Center for Justice affirm that systematic arbitrary detention, enforced disappearance, and torture resulting in death, as in the cases of Mohammed Al-Shami and Ahmed Baalawi, may constitute crimes against humanity and war crimes under Articles 7 and 8, respectively, of the Rome Statute of the International Criminal Court.
The experts further state that the Houthi militia has flagrantly disregarded the Convention on the Privileges and Immunities of the United Nations (1946) and the Convention on the Safety of United Nations and Associated Personnel (1994). They stress that these crimes are not subject to statutes of limitations and that Houthi political, security, and judicial leaders bear individual criminal responsibility for their involvement. Those potentially implicated include commanders of the Houthi Security and Intelligence Service and judges of the Specialized Criminal Court in Sana’a, who may be subject to prosecution before courts exercising universal jurisdiction.
Human rights activists who spoke to ACJ argue that the United Nations’ continued handling of the cases of the 70 remaining detainees through muted diplomatic statements and undisclosed negotiations has emboldened the Houthi militia to expand its campaign of abductions, ultimately resulting in the deaths of personnel through torture and medical neglect.
The activists called on the UN Secretary-General and the UN High Commissioner for Human Rights to establish an urgent, independent international commission of inquiry into the deaths of Al-Shami and Baalawi and to make all findings public.
They also called for the suspension of all nonessential coordination with the Houthi authorities in Sana’a and the completion of the transfer of UN agencies’ headquarters, administrative operations, and financial functions to the interim capital, Aden, to safeguard personnel and ensure the independence of humanitarian operations.
In addition, they urged the activation of legal and financial protection mechanisms for the families of locally recruited UN personnel, ensuring that they receive the same emergency protection and response measures afforded to internationally recruited staff.
Legal experts and human rights activists also called on the United Nations Security Council and countries sponsoring the peace process to immediately impose international sanctions on Houthi security and judicial officials implicated in the abduction, torture, and prosecution of UN personnel.
They further urged that the immediate and unconditional release of all 70 detainees, together with the dismissal of the fabricated charges brought against them, be made a prerequisite for any political or economic agreements with the group.
Finally, they stressed the need for coordinated efforts among international human rights organizations to document cases of “death in custody resulting from torture” and “death following release” in Houthi detention facilities and submit the evidence to international accountability mechanisms to ensure that those responsible are held accountable and do not escape justice.
