North Korean Nuclear Test Was Twice The Size of Previous Test

The Comprehensive Nuclear-Test-Ban Treaty Organisation has confirmed that the nuclear test by North Korea was twice as powerful as the 2009 explosion and it registered 4.9 on the Richter scale.

Official sources in North Korea are claiming that Pyongyang had successfully tested a miniaturised  nuclear device which can be used by the North Korean Ballistic missiles. Early details suggest that North Koreans were able to improve over the previously tested nuclear device.
