North Korea confirms underground nuclear test

North Korea has successfully carried out an underground nuclear test of a new, “miniaturised” device, state media says.

State-run Korean Central News Agency (KCNA) said the test was conducted in a safe manner and is aimed at coping with “outrageous” US hostility that “violently” undermines the North’s peaceful, sovereign rights to launch satellites.

“The high-level nuclear test, unlike in the past, had more explosive power and involved a miniaturised and lighter atomic bomb and was staged safely and perfectly,” KCNA said.

The announcement came after seismic activity measuring 4.9 magnitude was registered on Tuesday by the US Geological Survey.

UN Secretary-General Ban Ki-moon condemned the test, saying it was “deplorable” that Pyongyang had defied international appeals to refrain from such provocative acts.

“The secretary-general condemns the underground nuclear weapon test conducted by [North Korea] today,” Ban’s spokesman Martin Nesirky said in a statement. “It is a clear and grave violation of the relevant Security Council resolutions.”

US President Barack Obama described the test as a “highly provocative act” that “undermines regional stability”.

Several other countries condemned the act, with Japan saying it was “extremely regrettable” and Russia calling it a violation of Pyongyang’s international obligations.

The UK said it would begin “urgent consultations with Security Council partners calling for a robust response”.

International concern
The announcement that the detonated device was “miniaturised” will raise alarm around the globe, with its suggestion that Pyongyang has mastered the technically complex process of producing a warhead small enough to fit on a long-range missile.

South Korean defence ministry spokesman Kim Min-seok, citing seismic data, said the test had an explosive yield of at least six or seven kilotons, significantly more than North Korea’s two previous tests in 2006 and 2009.

The South Korean defence ministry raised its military alert level, saying the country was on alert for additional nuclear activity or a missile launch.

The UN Security Council will meet at 14:00 GMT on Tuesday for emergency consultations.

“Diplomats here certainly believe it was a nuclear test,” Al Jazeera’s James Bays, reporting from the UN, said. “All the countries around that table, I think, will condemn what happened. The question is what action they will take.”

South Korea is the current president of the 15-country Security Council and had been calling for strong action against its neighbour in the event of a nuclear test.

China, the isolated North’s closest ally, had made a special effort to try to head off the bomb test, said a UN diplomat who has taken part in recent consultations.

“The Chinese gave the North Koreans a strong warning against carrying out a test as it became apparent that it was imminent,” said the diplomat, speaking on condition of anonymity.

China has “special means of communications” with the entourage of North Korean leader Kim Jong-un, the envoy added.

After the Security Council voted to extend sanctions on North Korea last month in response to its December rocket launch, the North warned the US that it was ready to carry out a nuclear test.

“North Korea’s announcements have become very vitriolic, even in the context of the last couple of years,” Al Jazeera’s Harry Fawcett, reporting from Seoul, said.

“They said they would be carrying out rocket launches, satellite launches, missile tests and key, a higher-level nuclear test – all of which they say could be targeted at the US.”
