The U.S. State Department said on Saturday it had imposed sanctions on a general of Iran's Islamic Revolutionary Guard Corps who commanded units blamed for a massacre of protesters in November.
The U.S. State Department has said previously it had received videos of the Revolutionary Guards opening fire without warning on protesters in Mahshahr county in southwest Iran. At least 148 people were killed.
The State Department said it was designating Shahvarpour, a commander in Khuzestan province where Mahshahr is located, under a U.S. law banning officials of foreign governments and their immediate family members for whom there was "credible information on their involvement in gross violations of human rights."
