North Korea announces it conducted nuclear test
North Korea says it has successfully carried out a hydrogen bomb test, which if confirmed, will be a first for the reclusive regime and a significant advancement for its military ambitions, according to CNN.
A hydrogen bomb is more powerful than plutonium weapons, which is what North Korea used in its three previous underground nuclear tests, CNN reports.
"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."
A senior U.S. administration told CNN it could take days to obtain the scientific data to determine whether this was a successful test.

The test took place at 10:00 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.
