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 disaster has prompted fears of a massive radioactive leak which could spark a Chernobyl- or Fukushima-style disaster.
As many as 200 North Korean labourers have been killed after a mine shaft being dug at the regime’s nuclear test site collapsed, according to Japan’s Asahi TV.
Sources in North Korea told the news channel that a tunnel being excavated by around 100 workers at the Punggye-ri test site collapsed earlier this month.
An additional 100 labourers sent to rescue their colleagues were reportedly killed when the tunnel suffered a second collapse.
An exact date for the disaster has not been provided, but it comes shortly after North Korea conducted its sixth – and most powerful – underground nuclear test at the site.
