South Koreans discovered four major infiltration tunnels after the Korean war, which North Koreans claimed at first were coal mines (they had painted the insides of the tunnels black to make it look like coal deposits). It was soon discovered, through obvious clues such as the direction of the dynamite explosions, that these tunnels were dug specifically for the purpose of invading Seoul in the shortest possible time. To this day Koreans believe there may be dozens of other undiscovered tunnels.
