The Office of Foreign Assets Control (OFAC), part of the U.S. Department of the Treasury, has announced sanctions against individuals now included on the Specially Designated Nationals and Blocked Persons List (SDN List). These individuals have been identified as involved in serious human rights abuses or corruption. As a result, all their properties and interests within the U.S. are blocked, and American citizens are not allowed to conduct any transactions with them. This action is part of OFAC's efforts to combat human rights abuses globally.
Simple Explanation
The U.S. government has put some people on a special list because they've done bad things, like being mean to others or stealing. Now, their stuff in the U.S. is frozen, and Americans aren't allowed to buy from or sell to them.
