Mexican drug lord Ismael "El Mayo" Zambada, one of the world's most powerful and wealthy crime bosses, was sentenced Monday to life in US prison for co-leading the notorious Sinaloa cartel. The 76-year-old is the former top associate of the organization's kingpin founder, Joaquin "El Chapo" Guzman, who is serving a life sentence in a maximum-security prison in Colorado.

He emphasized that the drug lord had not provided US authorities any information on other cartel members or Mexican government officials.
