North Korea conducts biggest nuclear test
Sept.9, Seoul: North Korea is believed to have carried out its fifth and largest ever test of a nuclear device, according to South Korean military officials.
South Korean President Park Geun-hye called it an act of "self-destruction" which showed the "maniacal recklessness" of leader Kim Jong-un. It was detected as a 5.3 magnitude quake close to the nuclear test site.
The North has not commented, but analysts fear this could be a sign of the rogue state's nuclear progress. Previous artificial earthquakes in the same area and of that magnitude have all been nuclear tests.
In a statement carried by the Yonhap news agency, South Korea's Joint Chiefs of Staff said: "We estimate the North has carried out the biggest-ever test." It said the yield was estimated to have been 10 kilotonnes, almost twice the power of its last test in January. At that time the North said it had successfully tested a hydrogen bomb, but many analysts cast doubt on that claim, BBC news reported.
The US Geological Survey, which monitors global seismic activity, said earlier that a tremor had been detected in the Punggye-ri nuclear test site in the north-east.
