 – The United States has issued fresh sanctions on 10 entities and four individuals based in Iran, Malaysia, Hong Kong and Indonesia that it accuses of supporting the production of Iranian drones, the Treasury Department said on Tuesday.

The network has facilitated the procurement of components worth hundreds of thousands of dollars for the Islamic Revolutionary Guard Corps Aerospace Force Self Sufficiency Jihad Organization and its drone program, the department said.

Iran‘s illicit production and proliferation of its deadly UAVs (unmanned aerial vehicles) to its terrorist proxies in the Middle East and to Russia continues to exacerbate tensions and prolong conflicts, undermining stability,” Under Secretary for Terrorism and Financial Intelligence Brian Nelson said in a statement.

Washington has long accused Tehran of supplying such weapons to Russia for use in Ukraine. Iran denies providing Russia with drones for use in the country.
