‘Shortcut’ tunnel at Punggye-ri nuclear testing centre could see it operational within a month, sources tell South Korean news agency
North Korea may be making rapid preparations to carry out a nuclear weapons test for the first time in more than four years, according to a South Korean media report.
The Yonhap news agency, quoting government sources, said North Korea appeared to be digging a “shortcut” to Tunnel 3 at its previously closed nuclear test site in Punggye-ri.
