Mexico is formally starting extradition proceedings against captured drug lord Joaquin 'El Chapo' Guzman, the attorney general's office said on Sunday.
The United States government wants Guzman tried on trafficking charges and he faces criminal proceedings in at least seven US courts.
Mexican officials say the government aims to carry out the procedure to extradite Guzman to the United States as fast as possible, though it still faces bids to block it by his lawyers.
