A 755ft (230m) tunnel used to smuggle drugs has been discovered running under the border between Mexico and the United States.
The tunnel linked a soon-to-be opened ice and purified water business in Sonora to a business in Arizona, the Mexican defence secretariat said.
Discovered by the Mexican army, the tunnel contains electricity, ventilation and small carts for transporting the drugs.
