MEXICO CITY (AP) — The U.S. Treasury Department is imposing sanctions on two sons of Sinaloa cartel drug lord Joaquin Guzman.
The department says it has designated Ivan Archivaldo Guzman Salazar and Ovidio Guzman Lopez under the Kingpin Act.
That prohibits people in the U.S. from doing business with them and freezes their U.S. assets.
The department said Tuesday Ovidio Guzman Lopez plays a significant role in the drug trafficking activities of his father, who is known as "El Chapo." He went on the list in 2001.
Ivan Guzman was detained on money laundering charges in Mexico in 2005, but was later released.
The department named two other alleged high-ranking Sinaloa cartel figures to the list. Both Noel Salgueiro Nevarez and Ovidio Limon Sanchez were detained in Mexico in 2011 and remain in custody.
