Two Colombians wanted on U.S. drug-trafficking charges have been extradited from Colombia and flown to the United States to stand trial, the U.S. Marshals Service said in Washington. Luis Carbacas, 60, is charged with leading a drug ring in North Carolina, and Rafael Juliao, 42, is charged with cocaine distribution in New York City. They will stand trial in the respective states. They are among 17 people extradited from Colombia since the government of Colombian President Virgilio Barco began its drive against the narcotics cartels last August.
