North Korea may soon conduct its sixth nuclear test in the face of the United States’ decision to move a carrier group toward the region.
Satellite imagery shows activity at the Punggye-ri testing site, analysts from 38 North, a U.S. research institute that monitors North Korea, wrote on its website Wednesday.
Foreign journalists inside the country were told to prepare for a “big and important event” Thursday, Reuters reported.
The analysts added that there was movement around one of the portals and in the main administrative area of the site as well as personnel seen at the command center.
South Korean officials downplayed any news signs that a test was coming, Bloomberg reported. South Korea’s Joint Chiefs of Staff spokesman Roh Jae-cheon told reporters that Seoul saw no signs that North Korea was preparing any sort of provocative actions. Officials added that Pyongyang has maintained such readiness that it could conduct a missile test without warning, according to Reuters.
