Drug-smuggling tunnels found on US-Mexican border

Authorities in the US have discovered two tunnels on the Mexico-US border that they claim have been used to smuggle drugs between the nations.
A 73-year-old woman has been arrested in connection with the tunnels, even though no drugs were found in them.
The tunnels are reported to link drug-smuggling warehouses in Tijuana, Mexico, with the Otay Mesa area of San Diego. Their discovery was announced by the US Immigration and Customs Enforcement’s Homeland Security Investigations in a statement last week.
One tunnel was 600 yards in length, and included a basic rail road and electric lightning. The other was longer, and had an electric rails system and ventilation.
According to the US authorities, the tunnels are among a number to have been discovered in recent years – giving rise to the thought that a cartel has been investing in the infrastructure to smuggle drugs between North and South America.
More generally, there is growing international awareness of a global pattern of drug smuggling between nations, using home-made infrastructure to circumvent official travel routes. For example, similar tunnels have been identified elsewhere, including inside a house in Nogales, Sonora.
Speaking about the latest find, US Attorney Laura Duffy observed: “Going underground is not a good business plan.”
