SEOUL (Reuters) - North Korea is ready to conduct an additional nuclear test at any time, South Korea's Defence Ministry said on Monday, three days after Pyongyang's fifth test drew widespread condemnation.
North Korea set off its most powerful nuclear blast to date on Friday, saying it had mastered the ability to mount a warhead on a ballistic missile and ratcheting up a threat that its rivals and the United Nations have been powerless to contain.
