North Korea said Saturday that inter-Korean relations have entered into a state of war and all cross-border issues will be dealt with in a wartime manner, the latest in a near-daily series of strident threats against the South in recent weeks.\"Situations on the Korean Peninsula, which are neither in peace nor at war, have come to an end,\" the North said in a special statement issued by the country\'s party, ministries and other institutions, according to the Korean Central News Agency.
