"By Marian Smith, Staff Writer, NBC News North Korea said on Saturday that it was entering a "state of war" with South Korea, following a call to arms by the country's young leader Kim Jong Un and days of increasingly belligerent rhetoric from the isolated state. The North's official news agency KCNA published the joint statement issued by the government, political parties and other organizations. "From this time on, the North-South relations will be entering a state of war and all issues raised between the North and the South will be handled accordingly," it said. "
