South Korea warns North Korea over new nuke test
South Korea's foreign minister warned North Korea on Tuesday that the cost of keeping and testing nuclear weapons will be so high that it could threaten the survival of Kim Jong Un's regime.


Yun Byung-se told a standing-room audience of diplomats, UN officials and Korea-watchers at the International Peace Institute that the North will pay "the heaviest price" in new sanctions if it defies the international community and goes ahead with a new nuclear test. (AP)
