United States on Thursday imposed sanctions on two Iranian Judges. US officials said that Revolutionary Court judge Abdolghassem Salavati had sentenced a recently freed American and also sent more than 100 people to jail for political reasons.

The Treasury Department also targeted another Revolutionary Court judge, Mohammad Moghisseh, who it said has presided over trials of artists and over anti-regime social media postings.

The sanctions make any transactions with the two judges a crime in the United States, with any assets they may have blocked. US secretary of state Mike Pompeo said that the United States would also restrict visas for Iranian officials over last month’s crackdown on protests, in which Amnesty International says more than 300 people died.
