The Trump administration unveiled new sanctions on Iran on Thursday. US President Donald Trump is continuing to sanction Iranian entities before he has to leave office next month.

The United States designated the Shahid Meisami Group and its director, Mehran Babri, the State Department said in a press release. The company is owned by the Iranian Organization of Defensive Innovation and Research, which was similarly sanctioned in 2014 under the administration of former President Barack Obama. The company has been involved in “the testing and production of chemical agents for use as so-called incapacitation agents,” the State Department said.

Shahid Meisami Group and Babri were sanctioned under Executive Order 13382, which deals with the proliferation of weapons of mass destruction. The order freezes any US assets of designated entities and prohibits US entities from doing business with them.

The Trump administration has continued its yearslong continuation of placing sanctions on Iran through Trump’s final weeks in office. On Nov. 10, the Department of the Treasury announced sanctions on companies allegedly involved in procuring goods for an Iranian military company.
