The latest test involved a 'miniaturized and lighter nuclear device'
(NEWSER) – In open defiance of the UN, North Korea has executed its third nuclear test, prompting global condemnation among leaders from the US to Russia to Japan.
The latest test involved a "miniaturized and lighter nuclear device with greater explosive force than previously" in 2006 and 2009, the country said.
Calling the test a "highly provocative act," President Obama has urged "swift and credible action by the international community," and the UN Security Council is planning a meeting this morning to address the issue, the New York Timesreports. Pyongyang said afterward that the test was a "first response" to US hostility and warned of unspecified "second and third measures of greater intensity."
