North Korea Moving To Test-Fire Long-Range Missile

SEOUL, Feb. 3 (Yonhap) -- In what appears to be its latest message to U.S. President Barack Obama, North Korea is preparing to test-fire its longest-range missile designed to deliver a nuclear warhead, South Korean officials and analysts said Tuesday.

A defense source in Seoul said U.S. and South Korean intelligence officials have recently spotted a North Korean train carrying what is believed to be a Taepodong-2 missile. The source added there will likely be a launch in a month or two.
