Photographs have been released of tunnels under one of the hideouts of Joaquín Guzman Loera, aka El Chapo, one of Mexico's most notorious drug lords. Guzman, who was captured in Mazatlan, had several safe houses dotted around.

Mexican attorney general Jesus Murillo Karam described an operation that took place in Culiacan focused on seven homes connected by tunnels and to the city's sewer system. The house doors were reinforced with steel, which delayed entry by law enforcement, presumably allowing Guzman to flee.
