New road construction and other upgrades are under way at North Korea's long-range rocket launch site, although there is no sign of preparations for a rocket launch or an engine test, a website monitoring the North said Thursday.
Commercial satellite imagery taken of the Sohae Satellite Launching Station "indicate upgrades are in progress at North Korea's main space launch facility, including new road construction throughout the site, new guard or observation positions and excavation near the launch pad, the purpose of which is yet unclear," the website 38 North said.
