The state media of North Korea claimed that Pyongyang successfully conducted a hydrogen bomb test. Earlier on Sunday, the United States Geological Survey had reported a possible explosion in North Korea, at a site where Pyongyang has detonated nuclear explosions in the past.
Pyongyang’s sixth underground test triggered a 6.3 magnitude earthquake that was felt in China’s Yanji, about 10km from North Korea’s Punggye-ri nuclear test site. The test caused a quake five to six times more powerful than the seismic activity recorded after Pyongyang’s fifth nuclear test.
South Korean President Moon Jae-In called for a National Security Council emergency meeting and Seoul’s military raised its alert level. North Korea’s assertions came even as United States President Donald Trump and Japanese Prime Minister Shinzo Abe talked over the phone about the escalating nuclear crisis in South East Asia.
However, North Korea provided no evidence of its claim. Pyongyang had twice in July tested intercontinental ballistic missiles that it claims to have a reach of around 10,000 kilometres, thus making them capable of striking the US mainland.
The North Korean move comes a few days after US President Donald Trump released a threat warning for the country saying, North Korea will be dealt with ‘fire and fury’ if it continues nuclear tests. Recently, North Korea fired missiles posing threat to Japan as well.
