"[C]onsistent with section 106 of Countering America’s Adversaries Through Sanctions Act of 2017, we are identifying and imposing sanctions on two individuals and one entity implicated in extrajudicial killings, torture, or other gross violations of internationally recognized human rights committed against individuals in Iran.  Bushehr Prison has reportedly been the site of several human rights abuses and Mohammed Reza Ostad was the warden of that facility while gross violations of human rights occurred there."¹
