The Telegraph:
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.
