A tunnel at North Korea’s nuclear test plant collapsed after Pyongyang’s sixth atomic test in September, feared to have killed more than 200 people, Japanese broadcaster TV Asahi said on Tuesday, citing unnamed sources familiar with the situation.
About 100 workers at the Punggye-ri nuclear site were affected by the initial collapse, which took place around September 10, the broadcaster Asahi 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 Sept. 3 has destabilized the region, and the Punggye-ri nuclear site may no longer be used to test nuclear weapons due to the adverse effects.
