New activity detected at North Korea’s nuclear testing facility

North Korea has essentially completed restoration work at its Punggye-ri Nuclear Test Facility and appears to be expanding construction activity into a second tunnel, according to a new analysis from the Center for Strategic and International Studies (CSIS).

The Washington DC-based think tank said commercial satellite imagery it obtained from June 14 showed “minor new activity” at Tunnel No 3 “, indicating that the refurbishment and construction work during the past four months [was] essentially complete, and the tunnel is now ready for the oft-speculated seventh nuclear test”.
