North Korea says it successfully tested a hydrogen bomb
Shortly after a 5.1 magnitude earthquake was detected in North Korea Wednesday, the country announced it successfully tested a hydrogen bomb.
"If there's no invasion on our sovereignty, we will not use nuclear weapon," the state news agency said. "This H-bomb test brings us to a higher level of nuclear power." North Korea said the test took place at 10 a.m. local time in the northeastern part of the country. Earlier, officials in South Korea declared that the earthquake was "artificial," and the foreign ministry called an emergency meeting to discuss the possibility of a nuclear test.
Hydrogen bombs are more powerful than plutonium weapons, and if North Korea has one in its arsenal, it would be a significant advancement, CNN reports. North Korea is believed to have a few crude nuclear weapons, and conducted its last atomic test in February 2013.
