Mexican authorities have uncovered a hidden tunnel from the northwestern state of Sonora to Arizona in the United States, the National Commission for Security said Sunday.
The discovery was made while Mexican police, inspecting a drainage pipe that crosses the border, noticed a difference in the surface of the concrete at one point, the CNS said.
After moving some material, the officers discovered a “secret excavation” of a tunnel that was nearly 1.5 meters long on Mexican territory and more than 30 meters long in the US.
Half of the tunnel was supported by wood beams and the rest was dirt and rocks – “apparently in the process of construction, without an exit on the surface,” the CNS said.
Authorities on both sides of the border periodically discover this type of hidden tunnel, typically used by drug traffickers or undocumented migrants. (AFP)
