WASHINGTON: The United States imposed sanctions Thursday on Iranian security officials and financial networks, accusing them of orchestrating a violent crackdown on peaceful protests and laundering billions in oil revenues. Treasury Secretary Scott Bessent announced the measures in the wake of the biggest anti-government protests in the history of the Islamic republic, although the demonstrations appear to have diminished over the last few days in the face of repression and an almost week-long Internet blackout.

The Treasury Department also announced sanctions against Iranians who help launder proceeds of Iranian petroleum and petrochemical sales.

New penalties come as Trump welcomes purported Iranian decision to halt execution of antigovernment demonstrators.
