A riot at the El Castillo Penitentiary Centre in Mazatlán, Sinaloa, left nine inmates and a minor visitor dead, and 16 inmates injured, state authorities reported. The Sinaloa Public Security Secretariat announced that the 16 injured inmates were transported for medical care. Security forces moved in to regain control of the facility, which remains under police supervision. Social workers are contacting the families of the deceased, and visits to the prison have been suspended as a precaution. Sinaloa, a hotspot for rival factions of the Sinaloa drug cartel, is one of six Mexican states the U.S. State Department advises Americans against visiting due to security concerns. Officials have not confirmed whether the prison violence was related to the cartel conflict.
