NOGALES, Ariz. (AP) - Authorities say an incomplete tunnel has been found under the U.S.-Mexico border in Nogales, Arizona, and Nogales, Sonora.
The U.S Border Patrol said Tuesday the presence of structural shoring and digging tools in the tunnel when it was discovered Monday indicated that its excavation was still in progress.
The Border Patrol said its agents and Mexican law enforcement personnel found the tunnel during a routine sweep to detect tunnels to prevent the illicit movement of contraband or people across the border.
According to the Border Patrol, the tunnel was adjacent to the main crossing in downtown Nogales and it ended under a parking lot in Nogales, Arizona.
The tunnel was described as approximately 50 feet (15 meters) long and 2 feet (0.6 meters) square. It will be filled with cement.
