"North Korea is restoring a tunnel to a nuclear test site it demolished in 2018, raising the specter of a nuclear test soon, a nonproliferation expert has written.
Writing for the Open Nuclear Network (ONN), a nuclear weapons risk mitigation program run by the Vienna-based One Earth Foundation, ONN senior fellow and former United Nations North Korea panel expert Katsuhisa Furukawa said the North is in the process of reactivating some parts of its mountainous nuclear weapons test site in Punggye-ri, North Hamgyong Province.
'These developments clearly show that the DPRK has reactivated, or is in the process of reactivating, some parts of the Punggye-ri nuclear weapon test site, especially the South Portal and the main administrative area,' he wrote, referring to the North by the acronym for its official name, Democratic People's Republic of Korea."
