U.S. Border Patrol officers and their Mexican counterparts found a partially constructed tunnel under a street in Nogales on Thursday.
The 29-foot tunnel contained construction equipment and wiring. No arrests were made.
The tunnel was the 123rd found in the Tucson Sector since 1990 according to the Border Patrol. Officials said since border wall construction and fortification began earlier this year they have not seen an increase in the number of tunnels.
They called that a "mini-victory."
