U.S. Border Patrol agents and Mexican law enforcement discovered an unfinished smuggling tunnel this week in the Arizona border city of Nogales.
The tunnel that extended 18 feet into the United States was still under construction and didn’t have an exit on the U.S side.
It was discovered Tuesday west of the DeConcini Port of Entry as part of a series of searches for tunnels.
Agents have found dozens of drug tunnels in Nogales since the 1990s.
The proliferation of tunnels is attributed to the government putting more border fencing, Border Patrol agents and technology at the border in recent years.
