The U.S. Treasury Department has sanctioned six top leaders of the Venezuelan prison gang Tren de Aragua, including its leader Niño Guerrero, and is offering a $5 million reward for his arrest. The gang, designated as a foreign terrorist organization, is involved in drug trafficking, human smuggling, and violent crimes across the Western Hemisphere. The sanctions block U.S. financial transactions with the designated individuals, and the Trump administration emphasizes its commitment to dismantling the gang’s influence.
