The sanctions have been slapped against Shahid Karimi Industries, Shahid Rastegar Industries, Shahid Cheraghi Industries, Shahid Varamini Industries, Shahid Kalhor Industries and Amir Al Mo'Menin Industries -- the subordinates of Shahid Hemmat Industrial Group (SHIG), an entity which the US says is central to Iran's ballistic missile programme.
Such a move by the Department of Treasury comes a day after Iran carried out launch of the Simorgh space launch vehicle. The test, however, was not successful.
"The US government will continue to aggressively counter Iran's ballistic missile-related activity, whether it be a provocative space launch, its development of threatening ballistic missile systems, or likely support to Yemeni Houthi missile attacks on Saudi Arabia such as occurred this past weekend.
"These sanctions target key entities involved in Iran's ballistic missile program, and underscore the US' deep concerns with Iran's continued development and testing of ballistic missiles and other provocative behaviour," said Treasury Secretary Steven T Mnuchin.
In addition, foreign financial institutions that facilitate significant transactions for, or persons that provide material or certain other support to, the entities designated today risk exposure to sanctions that could sever their access to the US financial system or block their property and interests in property under the US jurisdiction.
