It seems that Mexico is not the only nation with smuggling tunnels.
Officials found a 700m tunnel...with its own train...under the border of Ukraine and Slovakia..along with 2.5 million cigarettes.
The 6m deep tunnel ran from the Slovak village of Vysne...to a new Ukrainian house in Uzhorod.
Police speculate that up to 50 million euros in taxes were evaded with the tunnel scheme.
A Slovak property owner was arrested.
