North Korea conducts 'potentially most powerful' nuclear test: Seoul

Seoul has confirmed that North Korea has conducted a fifth nuclear today which is potentially its most powerful yet.

According to CNN, seismic activity, with a magnitude of 5.3, was detected near Punggye-ri, Kilju County, which is the same location as four other tests, the most recent of which was in January.

Condemning the test, South Korea said that it was a clear violation of the United Nations Security Council resolution.

Branding Kim Jong Un's regime as "fanatically reckless", President Park Geun-hye said that, "the only thing that Kim Jong Un regime can gain from the nuclear tests is stronger sanctions from the international community and its isolation. Such provocation will eventually hasten its path to self-destruction,"

The blast had the explosive power of 10 kilotons, almost twice as large as the previous test, said Kim Nam-wook, from South Korea's Meteorological Administration.

By comparison, the nuclear bomb dropped on Hiroshima was 15 kilotons.
