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."
South Korean defense ministry said it could not immediately confirm whether the test was what the North claimed it was, but the country's foreign ministry hastily convened an emergency meeting.
