North Korea lashed out at U.S. Secretary of State Marco Rubio for calling it a “rogue” state and warned Monday that such “coarse and nonsensical remarks” will never contribute to U.S.

Though North Korean ballistic missiles account for only a small portion of Russia's missile strikes they carry a large warhead of up to one tonne and have a range of up to 800 km, the military source said. The Iskander-M, an equivalent Russian missile, carries a smaller payload and has a shorter range of 500 km.
