The Treasury Department on Nov. 8 announced a set of targeted sanctions against Iranian individuals and entities directly engaged in domestic human rights abuses, censorship activities, and support for international terrorism.

“Today’s designations further demonstrate our resolve to put a stop to the Iranian regime’s continued efforts to deny the Iranian people access to information and the ability to speak freely,” said Under Secretary for Terrorism and Financial Intelligence David S. Cohen.

In July, Congress passed the Iran Threat Reduction and Syria Human Rights Act, which mandates tough new sanctions on Iranian entities that engage in censorship activity and on individuals who engage in serious human rights abuses. The law also mandates sanctions on entities providing assistance to Iran’s Islamic Revolutionary Guard Corps (IRGC).

With this action, the Treasury Department designated four entities controlled by the IRGC for providing support to the group, including the state-owned National Iranian Oil Company, which is responsible for the country’s oil exports.

U.S. citizens are also now prohibited from engaging in transactions with the sanctioned entities, and any assets they may have under U.S. jurisdiction will be frozen.
