Mexico's attorney general's office and the security ministry confirmed that officials were handing over 29 cartel figures to the U.S.

A Mexican drug lord who was one of U.S. authorities’ most wanted men has been brought into a New York courtroom to answer charges that include orchestrating the 1985 killing of a U.S. federal agent.
