The U.S. Department of the Treasury's Office of Foreign Assets Control (OFAC) has announced updates to the Specially Designated Nationals and Blocked Persons List (SDN List). These updates include the addition of certain individuals and vessels linked to entities involved in terrorism or sanctioned activities, resulting in the blocking of their property and interests within U.S. jurisdiction. Moreover, the penalties imposed under the Countering America's Adversaries Through Sanctions Act (CAATSA) have been applied to the GHEZEL HESAR Prison in Iran, citing involvement in human rights abuses. These measures restrict U.S. persons from engaging in transactions with the listed parties.
Simple Explanation
The U.S. Treasury's special office is blocking some people and boats because they did bad things, like helping terrorists. This means Americans can't do business with them.
