A TUNNEL at an underground North Korea nuclear site has collapsed with up to 200 people killed, according to reports.
The collapse happened at the Punggye-ri nuclear test site in the north-east of the country on October 10, according to Japan’s TV Asahi.
The accident is believed to have been caused by Kim Joing-un’s sixth nuclear test which weakened the mountain, according to the report.
It was reported earlier this year that the mountain under which the base is believed to be hidden was at risk of collapsing and leaking radiation into the region.
They posted an analysis of data collected from more than 100 seismic monitoring sites across China.
This has narrowed down the location of Pyongyang’s nuclear tests with a margin of error of just 100m. They’ve all been under the same mountain.
Seismic data showed the underground test triggered an earthquake of magnitude 6.3, around ten times more powerful than the fifth test a year ago.
