A N Korea nuclear-tipped ICBM will cross 'red line': S Korea's Moon

Seoul

NORTH Korea would be "crossing a red line" if it put a nuclear warhead on an intercontinental ballistic missile, South Korea's president said on Thursday, but the United States had promised to seek Seoul's approval before taking any military action.

North Korea's rapid progress in developing nuclear weapons and missiles capable of reaching the US mainland has fuelled a surge in tensions in recent days. Pyongyang has threatened to fire missiles towards the Pacific island of Guam and US President Donald Trump has warned it would face "fire and fury" if it threatened the United States.
