Mexico finds smuggling tunnel near US border

The Mexican army said the tunnel was found Thursday after authorities received an anonymous call in the border city of Nogales, Sonora, south of Arizona. U.S. law enforcement officials confirmed that the Mexican military had discovered the football field-long tunnel with elaborate electricity and ventilation systems.

U.S. Border Patrol spokesman Victor Brabble said the tunnel did not cross into the U.S.

The army said the anonymous caller was reporting gunmen standing outside a two-story house in a hilly neighborhood near the international bridge where motorists travel between Mexico and the United States.

Inside the house, soldiers discovered a fake wall inside a storage closet under a staircase that led to a dark room with buckets and clothes. After lifting a drain cover in that room, soldiers found another staircase at the entrance of the tunnel that went 16 feet underground and measured a yard in diameter. Light bulbs lit the underground passage and pipes stretched across the 120-yard tunnel that Mexican army officials believe was built to smuggle drugs.
