The U.S. Treasury Department has imposed a fresh round of sanctions on several individuals and entities linked to Iran, according to a notice posted on the agency’s website. The action broadens Washington’s effort to pressure Tehran by restricting the designated parties’ access to the U.S. financial system and blocking any assets they may hold under U.S. jurisdiction. Treasury officials did not immediately disclose the names of the targeted parties or the specific activities that led to the designations. The move follows a series of Iran-related sanctions rolled out earlier this year and underscores the Biden administration’s continuing reliance on economic measures to confront Iran’s regional influence and nuclear ambitions.
