The US at the same time said it can not confirm the claim of North Korea.

But a confirmed test would be seen as extremely worrying and lead to a strong push for new, tougher sanctions on North Korea at the United Nations.
China, a close ally of North Korea, earlier said it “firmly opposed” the nuclear test, and chided Pyongyang for having gone through with it “irrespective of the global community’s opposition”.
North Korea said it successfully tested a miniaturised hydrogen nuclear device, which would mark a significant advance in the isolated state’s technological capability.
South Korea has said it would “take all possible measures” against its northern neighbour after todays nuclear bomb test.
“We condemn any violation of UNSC Resolutions and again call on North Korea to abide by its global obligations and commitments”, Price said.
Japanese Prime Minister Shinzo Abe slammed it as “a serious threat to the safety of our nation”.
South Korean President Park Geun-hye, who called an emergency meeting of the National Security Council, termed North’s alleged thermonuclear device test a “grave provocation” against national security.
The test, just two days ahead of leader Kim’s birthday, was initially detected by global seismology monitors as a 5.1-magnitude tremor next to North Korea’s main nuclear test site.
– The White House says it can’t confirm a North Korean nuclear test, but said the USA would condemn any violations of United Nations Security Council resolutions.
The claim was questioned by worldwide experts and there was continued scepticism over Wednesday’s test announcement.
The test has “proved the technological specifications of the newly developed H-bomb were accurate and scientifically verified the power of smaller H-bomb”, said the statement.
According to an AP report, North Korea conducted its third nuclear test in February 2013. He further said that it is high time, that the worldwide community finds a way beyond the paper resolutions to impose some real punishment on the country for continuing with its nuclear testing mission.

Since the elevation of young leader Kim Jong Un in 2011, North Korea has ramped up angry rhetoric against the leaders of allies Washington and Seoul and the U.S.-South Korean annual military drills it considers invasion preparation. That places the epicenter at Pyunggye-ri, where all of North Korea’s three known nuclear tests have been conducted in 2006, 2009 and 2013.
