The U.S. Treasury Department has sanctioned a Mexican businessman and four companies, including two newspapers, for links to drug trafficking.

The Treasury Department has added Naim Libien Tella and the Mexico-City based publication Unomasuno to its so-called "kingpin list" for providing support to Los Cuinis drug cartel and its leader Abigael Gonzalez.

The designation Wednesday freezes any U.S. assets belonging to Libien and the companies, and U.S. people and companies are generally prohibited from doing business with them. Libien is vice president of Unomasuno, founded in the 1970s as an opposition newspaper to the ruling Institutional Revolutionary Party or PRI.

Other companies listed include the Toluca-based newpaper, Diario Amanecer, and Aerolineas Amanecer, an air taxi company. Both are owned or controlled by Libien, the Treasury Department statement says.
