Washington has expanded its crackdown on Iran’s weapons ecosystem by sanctioning two Ukrainian companies accused of quietly feeding Tehran’s drone program. The Treasury Department said the firms acted as procurement fronts that channelled aerospace components to Iran’s state-owned drone manufacturer, a supply line now linked to battlefields stretching from Ukraine to the Middle East.

The announcement forms part of a sweeping sanctions package targeting 32 individuals and entities across Europe, Asia, and the Middle East. The shared thread, according to US officials, is support for Iran’s ballistic missile development and its expanding fleet of uncrewed aerial vehicles.

At the centre of this latest action are GK Imperativ and Ekofera, two companies registered in Kharkiv and Kyiv. Washington says both firms helped Iranian agents secure parts for the Iran Aircraft Manufacturing Industrial Company, known as HESA. The manufacturer builds the Shahed series of loitering munitions and the Ababil family of drones
