According to satellite images published by CNN, Pyongyang has upgraded the Yeongjeo-dong missile base in North Korea's mountainous interior and has built up another facility that had not previously been publicly identified.
While the base at Yeongjeo-dong has always been known to USA intelligence agencies and analysts, researchers at the Middlebury Institute of International Studies at Monterey told CNN that the images reveal construction on a new facility just seven miles away from the older site that had not been previously publicly identified.
North Korea has "significantly" expanded a key long-range missile base, while denuclearization negotiations with the United States have stalled, CNN reported Wednesday, citing new satellite imagery.
"Construction on the previously unidentified site has continued even after the Singapore Summit" between Kim and President Donald Trump in June, Jeffrey Lewis of the Middlebury Institute, one of the analysts that identified the site, told CNN.
It hasn't. And experts were warning Trump all along that it wouldn't, because Kim sees nuclear weapons as an essential tactic for his own survival.
Experts told the USA news network that the site´s location made it suitable to host North Korea´s newest long-range missiles, including ones that could carry nuclear warheads.
It's the latest in a series of reports suggesting that North Korea continues to develop its missile programs short of an agreed plan with the United States to dismantle them.
In a statement the Pentagon said: "We watch North Korea very closely but we can not discuss intelligence". "We will not discuss matters of intelligence".
