North Korean nuclear test confirmed in major escalation by Kim Jong-un

 North Korea claims successful nuclear test

Regime confirms sixth nuclear detonation following earthquake that was detected by China, South Korea and the US

North Korea says it has tried a capable nuclear bomb that can be stacked on to an intercontinental ballistic rocket, in a move that is relied upon to build weight on Donald Trump to defuse the developing atomic emergency on the Korean promontory.

In a declaration carried on state TV, North Korea said the test, its 6th since 2006, had been a "total achievement" and included a "two-organize nuclear weapon" with "exceptional" quality.

There has been no free check of the North's claims that it has accomplished a key objective in its atomic program - the capacity to scale down a warhead with the goal that it can fit on a long-separate rocket.

Hours sooner, the administration discharged film of what it asserted was a nuclear bomb that would be stacked on to another ICBM.

The TV declaration – joined by devoted music and pictures of North Korean landscape and military equipment – said the test had been requested by the nation's pioneer, Kim Jong-un.

The blast was proclaimed by a 6.3-extent seismic tremor around six miles (10km) from North Korea's Punggye-ri atomic test site in the north-east of the nation. It was felt over the Chinese fringe in Yanji.

South Korea's meteorological organization assessed the shoot yield at between 50 to 60 kilotons, or five to six times more grounded than North Korea's fifth test in September a year ago.

Kim Young-charm, the head of South Korea's parliamentary resistance board of trustees said later that the yield was as high as 100 kilotons. One kiloton is proportionate to 1,000 tons of TNT.

The past atomic impact in North Korea is evaluated by specialists to have been around 10 kilotons.
