The unfinished tunnel discovered by authorities in Tijuana designed to smuggle drugs into the United States.

An Immigration and Customs Enforcement spokeswoman said Thursday that an approximately 220-yard passage, pictured at right, was lit and ventilated. It began under a bathroom sink inside a warehouse in Tijuana and did not cross the border into San Diego.

AP's report on the incomplete tunnel from Tijuana also mentions another found recently in Arizona:

Elsewhere, a 240-yard completed passage was discovered less than a week ago near Yuma, Ariz. U.S. authorities say that tunnel was operational.
