A reported earthquake in North Korea Wednesday raised suspicion that the secretive nation has conducted its first nuclear weapons test in more than two years, in defiance of continuing UN sanctions.
Shortly after the seismic tremor, North Korea said it had conducted a successful hydrogen bomb test, the Associated Press tweeted. A hydrogen bomb is generally considered to be more powerful than a typical nuclear explosive.
The U.S. Geological Service reported that a magnitude-5.1 earthquake occurred 30.4 miles from the city of Kilju, North Korea, where the country's Punggye-ri nuclear test site is located.
That is the same area where North Korea conducted nuclear tests in 2006, 2009 and 2013.
