“The State Department on Friday designated the Houthis as a terrorist organization, following through on a mid-January warning to crack down on the Yemen-based militant group. The action officially labels the Houthis as a Specially Designated Global Terrorist group, a step that gives the United States new powers to crack down on the Iran-backed Houthis’ access to the global financial system. It restores a designation given to the group late in the Trump administration, which Secretary of State Antony J. Blinken reversed soon after taking office in 2021, partly to facilitate peace talks for Yemen’s civil war. Last month, Mr. Blinken announced the State Department’s intent to return the Houthis to its terrorism list, but delayed the action for 30 days. The pause was intended in part to give humanitarian aid groups working in Houthi-controlled areas of Yemen time to ensure that their work does not run afoul of new sanctions from the United States that will punish anyone who provides support to the militant group. Some aid groups have warned that their work will inevitably be constrained in a country with dire humanitarian needs.”
