U.S. sanctions Iranians who aided Houthi rebels

The Treasury Department announced on Tuesday sanctions against five Iranian individuals who have played a part in providing the Houthis in Yemen with "ballistic missile-related technical expertise...on behalf of the Islamic Revolutionary Guard Corps-Qods Force."

Flashback: On Monday, Secretary of State Mike Pompeo said, "sanctions are going back in full effect and new ones are coming. ... We will track down Iranian operatives...and we will crush them." Behnam Ben Taleblu, research fellow at the Foundation for Defense of Democracies, told Axios this is "reflective of a brief uptick" in designations against Iran, and could "convince U.S. adversaries and allies alike that Washington will enforce the sanctions it has reimposed on Iran.”
