North Korea’s Kim vows to ‘put an end’ to South Korea if force is used

North Korean leader Kim Jong Un has vowed Pyongyang would not hesitate to “put an end” to South Korea if attacked, state media said Friday, as relations between the neighbors hit new lows.

The nuclear-armed North this year declared South Korea its “principal enemy”, closed agencies dedicated to reuni-fication and outreach, and threatened war over “even 0.001 millimeters” of territorial infringement.
