New tunnel beneath N. Korean mountain eyed as nuke test site

WorldTribune.com: "SEOUL — South Korea's National Intelligence Service reported that North Korean engineers have dug a tunnel 700 meters, about two-fifths of a mile, beneath the surface of Mount Mantap in North Hamkyong Province.

Word of the tunnel comes from Chung Hyung-Keun, a member of the National Assembly’s intelligence committee. Chung, who belongs to the conservative Grand National Party, revealed the tunnel’s existence after returning from a trip to Washington in which he advised against transferring wartime control of South Korean troops from U.S. to Korean command.

Chung said the tunnel resembles sites of underground tests in Nevada, India and Pakistan. The vertical shaft, near a horizontal tunnel, is about twice the necessary depth — a possible precaution against atmospheric fallout." More.
