North Korea has carried out its sixth nuclear test, Japan’s foreign minister says and this has also been confirmed by the State controlled North Korean press.
“The government confirms that North Korea conducted a nuclear test after examining information from the weather agency and other information,” Taro Kono told reporters.
Seismologists earlier detected a tremor in an area where North Korea has conducted previous nuclear tests.
The tremor was detected hours after North Korean leader Kim Jong-un was pictured with what state media said was a new type of hydrogen bomb.
State media said the device could be loaded on to a ballistic missile. Neither claim could be independently verified.
South Korean officials said the quake took place in Kilju County, where the North’s Punggye-ri nuclear test site is situated.
The “artificial quake” was 9.8 times more powerful than the tremor from the North’s fifth test, the state weather agency said.
