More than 20 tons of marijuana have been seized after the feds discovered a sophisticated, drug-smuggling tunnel measuring more than seven football fields in length between San Diego and Tijuana, Mexico.

The most recently found tunnel extended from a kitchen in Mexico to two warehouses in the Otay Mesa industrial complex in San Diego.
