North Korean leader Kim Jong Un reminded his troops to treat South Korea as a hostile foreign enemy and insisted that the North wouldn’t hesitate to attack its rival if the South infringes upon its sovereignty,

SEOUL (Reuters) -North Korean leader Kim Jong Un said South Korea is a foreign and hostile country, state media KCNA said on Friday. The remarks come a day after KCNA said North Korea's national assembly amended the constitution to designate South Korea a "hostile state",

The move fulfils Kim Jong Un's call for a constitutional amendment labeling Seoul the main enemy and follows the destruction of transport links to the South.
