The United States has imposed terrorism-related sanctions on three Nigerian currency exchange companies accused of helping finance ISIS West Africa.

The sanctions were announced by the U.S. Treasury Department’s Office of Foreign Assets Control in coordination with the State Department.

U.S. authorities identified Nigerian national Mukhtar Adam Muhammad as an alleged financial facilitator for ISIS West Africa and accused him of conducting financial transactions and providing services that supported the group’s activities.

The move highlights growing counterterrorism cooperation between Washington and Abuja and ongoing efforts to disrupt financial networks linked to extremist organizations.
