TOKYO - 3 September 2017: North Korea has conducted a sixth nuclear test, the Japanese government said as quoted by Sky news.
Seismological data from the United States Geological Survey (USGS) showed that an explosion caused a 6.3-magnitude tremor in the country's northeast, not far from the country's Punggye-ri nuclear test site.
If the initial data holds, it would make it the most powerful weapon that the Democratic People's Republic of Korea, as the country is officially known, has ever tested.
"After analyzing data provided by the Japan Meteorological Agency, the Japanese government concluded that North Korea has conducted a nuclear test," Japanese Foreign Minister Taro Kono said in a live television broadcast.
