The statement said that the DPRK succeeded in the H-bomb test, a great deed of history that reliably guaranteed the eternal future of the Korean nation and an event to go down in the national history.

The H-bomb test is a just measure for self-defense for thoroughly defending the sovereignty of the country and the vital right of the nation and reliably guaranteeing the peace in the Korean Peninsula and security in the region from the nuclear threat and blackmail by the U.S.-led hostile forces, the statement stressed.
