U.S. law enforcement found an unfinished but fairly well equipped underground tunnel on the U.S.-Mexico border. This was reported by The New York Post on August 7.
It is reported that the underground passage of more than 1.3 thousand feet long was coming from San Luis, Arizona, to San Luis Rio Colorado in Mexico.
The underground passage was about 1 m wide and 1.2 m high.
The unfinished aisle had a ventilation system, water supply, electrical wiring, and even a narrow gauge.
The tunnel was dug after a failure was discovered in mid-July at the US-Mexico border.
