[Ynet] Satellite photos show signs of new tunnel work at North Korea's underground nuclear test site, a US research institute said Tuesday.
The US-Korea Institute at Johns Hopkins School of Advanced International Studies said in an analysis that it does not appear to indicate another underground blast is imminent at the Punggye-ri site in the country's northeast. But it suggests North Korea has continued to work on its nuclear weapons program despite a recent easing of the tensions that followed its atomic test in February. |
