Sophisticated drug tunnel found along US-Mexico border

US authorities on Wednesday shut a sophisticated drug smuggling tunnel dug under the US-Mexican border. The tunnel, 2.4 miles long, sporting lights, ventilation and electric railway, linked a warehouse in Tijuana in Mexico to another in San Diego, California. The tunnel's discovery led to the seizure of 8.5 tons of marijuana and 327 pounds of cocaine, as per court records.
