The 13 businesses are accused of working with the Jalisco New Generation Cartel, a group designated by the U.S. government as a foreign terrorist organization.

The U.S. Treasury Department has imposed sanctions on more than a dozen Mexican companies and four people it says worked with a powerful drug trafficking cartel to scam elderly Americans in a multimillion-dollar timeshare fraud.

As part of its crackdown on gangs, the US Justice Department has offered $26m in rewards for Carteles Unidos leaders.
