North Korea threatens stronger action after nuclear test

“Second and third measures of greater intensity if Washington maintains its hostility” were threatened by Pyongyang Tuesday after its latest nuclear test, the third in a series. North Korea’s “detonation of a miniature atomic bomb” was universally condemned – even China voiced opposition. US officials said North Korea may now be planning to test a missile. US President Barack Obama called North Korea’s third successive nuclear test a "highly provocative act" that "undermines regional stability” and constitutes "a threat to US national security.” The UN Security Council is preparing a resolution of condemnation at a special emergency session.
