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.
North Korea claims the September 3 test beneath Mount Mantap was of a hydrogen bomb, with monitors suggesting the detonation was equivalent to an earthquake with a magnitude of 6.1 on the Richter scale.
Some analysts put the yield of the weapon as high as 280 kilotons, while seismologists picked up signs of underground collapses in the hours and days after the blast.
On October 17, a study published by the US-Korea Institute at Johns Hopkins University and published on the 38 North web site suggested the sixth underground test at the site had caused “substantial damage to the existing tunnel network under Mount Mantap”.
It added that there is a possibility that the site is suffering “Tired mountain syndrome”, although there were no indications that it was being abandoned for future nuclear tests.
Nam Jae-chol, the head of South Korea’s Meteorological Administration, warned in testimony before parliament on Monday that further tests at Punggye-ri could cause the mountain to collapse and release radioactivity into the environment.
“Based on our analysis of satellite imagery, we judge that there is a hollow space, which measures about 60 metres by 100 metres beneath Mount Matap”, he said. “Should another nuclear test take place, there is a possibility [of a collapse]”.
Chinese scientists have issued similar warnings, suggesting that nuclear fallout could spread across “an entire hemisphere” if the mountain did collapse.Source: The Telegraph UK
