“Yemen’s Houthi rebels stormed the headquarters of the United Nations’ Human Rights Office in the capital, Sanaa, seizing documents, furniture and vehicles, a senior U.N. official said Tuesday. The seizure was the latest move in a crackdown by the Houthis on people working with the U.N., aid agencies and foreign embassies. The crackdown comes as the Iranian-backed rebels have been targeting shipping throughout the Red Sea corridor over the Israel-Hamas war in the Gaza Strip. The rebels took over the U.N. Human Rights Office’s premises in Sanaa on Aug. 3, after forcing U.N. Yemeni workers to hand over belongings, including documents, furniture and vehicles, U.N. Human Rights Chief Volker Türk said in a statement. “Ansar Allah forces must leave the premises and return all assets and belongings immediately,” Türk said, using the official name of the Houthis.”
