A 15-foot underground high-tech tunnel has been discovered under the cities of Nogales, Mexico and Nogales, Arizona. It is the eighth such tunnel that has been discovered in the area over the last seven months.
The tunnel was discovered earlier this month but U.S. Border Patrol has just made the discovery public. The tunnel is considered quite sophisticated in terms of its structure.
The tunnel had electricity, water pumps and air ventilation systems in it. The tunnel was discovered inside an abandoned building in Mexico running 250 feet between both countries.
