Researchers have identified a covert North Korean ballistic missile base that has never been disclosed by the Kim Jong Un regime, says a new report published days after the White House announced that President Trump and North Korean leader Kim will meet in February.

According to a report from Beyond Parallel, a project sponsored by the Center for Strategic and International Studies, the Sino-ri Missile Operating Base is just one of up to 20 missile sites that the rogue regime has kept hidden. The site is also the headquarters for the Korean People’s Army Strategic Rocket Forces missile brigade and has been critical in forming ballistic missiles that can reach as far as Japan and Guam.
