Mexican Officials Discover Another Tunnel In Tijuana

Police in Tijuana, Mexico, have discovered a narrow tunnel under the border into the US. Officials say it was used to smuggle drugs and possibly undocumented migrants. More than 50 tunnels have been discovered under the US-Mexico border. Increased border surveillance following 9-11 is thought to have prompted drug smugglers to go underground to avoid detection.The latest discovery was made inside an area guarded by Mexican Treasury Department officials. Officials are investigating how the 32-foot long tunnel was able to operate so close to where federal officials were on duty. Authorities found shovels, lanterns, batteries and other tools, but no drugs. US officials have been filling at least six tunnels along the 2,000-mile border, at a cost of $2.7 million.
