Mohammad el Shami, who worked at the UN Human Rights Office in Yemen, died after being arbitrarily held by the Houthi rebel group since June 6, 2024, according to a statement from UN High Commissioner for Human Rights Volker Türk. His family said they were informed of his death only recently, more than a month after it occurred, and have not received any explanation of the cause or circumstances. Türk expressed his condolences and called for a prompt, independent and thorough investigation.

Türk said the Houthi authorities must disclose all relevant medical and detention records, preserve evidence and allow independent scrutiny of any stated cause of death. “There must be accountability for wrongdoing,” he said.

In addition to demanding an investigation into Shami’s death, Türk reiterated his call for the immediate and unconditional release of all other UN personnel held by the Houthis, including seven colleagues from his office, as well as humanitarian and civil society workers. He expressed grave concern for their safety and wellbeing.

Yemeni Prime Minister Shaya al-Zindani condemned the death, stating the Houthis “bear full responsibility.” He confirmed that more than 70 UN staff members and dozens of humanitarian workers remain in Houthi custody.

The Houthi group has previously stated that a number of individuals they detained were part of a US-Israeli “spy network.” They have also accused humanitarian organizations of using their work as cover for intelligence activities, though they have not provided evidence to support these claims.
