More than 200 people believed to be dead following collapse of a tunnel at North Korea’s nuclear test site after sixth atomic test in September.
The Reuters has published a report over the incident quoting Japanese broadcaster TV Asahi on Tuesday using unnamed sources familiar with the situation.
About 100 workers at the Punggye-ri nuclear site, located in Kilju County, North Hamgyong Province of North korea, were affected by the initial collapse, which took place around September 10, the broadcaster said.
A second collapse during a rescue operation meant it was possible the death toll could have exceeded 200, it added.
Experts have said a series of tremors and landslides near the nuclear test base probably mean the country’s sixth and largest blast on September 3 has destabilised the region.
The Punggye-ri nuclear site may not be used for much longer to test nuclear weapons.
