http://www.cnn.com/2016/01/05/asia/north-korea-seismic-event/index.html[quote]North Korea says it has successfully carried out a hydrogen bomb test in a region of the country where it conducted three previous nuclear tests.
If the claim is verified, a hydrogen bomb test will be a significant advancement for the country's military ambitions: the device is more powerful than plutonium weapons, which is what North Korea has previously tested
"If there's no invasion on our sovereignty we will not use nuclear weapon," the North Korean state news agency said. "This H-bomb test brings us to a higher level of nuclear power."
The test took place at 10 a.m. local time, the regime said in a televised statement.
The seismic event, which measured the event at a magnitude of 5.1, occurred 19 kilometers (12 miles) east-northeast of Sungjibaegam, the United States Geological Survey said.
