A tunnel running seven-tenths of a mile was discovered from Tijuana, Mexico to Otay Mesa, California. The authorities found two tons of marijuana inside the tunnel. Officals are calling it the most sophisticated and largest known tunnel to date that crosses the border.
The tunnel was equipped with lighting, electricity, ventilation and a pump to remove water. It stands 5 feet high and 3.5 feet wide.
Since 9/11 more that 20 cross-border tunnels have been discovered.
