The agency said Friday the tunnel spotted Wednesday was connected to a storm drain that runs into the United States from Mexico. NOGALES, Ariz. - The U.S. Border Patrol says its agents and Mexican federal police discovered an incomplete cross-border tunnel under a parking lot in Nogales. Border Patrol says the tunnel, as well as digging and cutting tools, was found during a sweep to help prevent illegal movement of contraband and people across the border. The agency said the tunnel extended 12 feet (4 metres) into the United States and 5 feet (1.5 metres) into Mexico.
