SEOUL, South Korea — North Korea is capable of detonating another nuclear device anytime at one of its unused tunnels at the country's main atomic test site, Seoul official said Monday, three days after the country carried out its fifth bomb explosion. South Korea's Defense Ministry spokesman Moon Sang Gyun refused to say what evidence pointed to another possible North Korea test. But he told reporters that South Korea and U.S. intelligence authorities believe North Korea has the ability to detonate another atomic device anytime. North Korea's pursuit of missiles and nuclear weapons is one of the most intractable foreign policy problems for the U.S. and South Korea. Six-nation negotiations on dismantling North Korea's nuclear program in exchange for aid were last held in late 2008 and fell apart in early 2009.
