‘Significant’ Activity Detected at North Korean Nuclear Test Site

“Significant” activity has been detected by commercial satellite at North Korea’s Punggye-ri nuclear test site.

According to 38North, a website which provides analysis on North Korea, substantial tunneling efforts have been observed in recent weeks at the mountainous location.

While Punggye-ri’s North Portal, the site of Pyongyang’s last five nuclear tests, remains inactive, equipment and personnel have recently appeared at the West Portal.
