Researchers have uncovered another secret operational ballistic missile base in North Korea - one of approximately 20 undeclared missile sites in the country - according to a new report released on Monday.
Beyond Parallel, a research project conducted by the Washington-based think tank Centre of Strategic and International Studies, identified the site as Sino-ri, a missile operating base that houses a regiment-sized unit equipped with Nodong-1 medium-range ballistic missiles.
CSIS researchers had previously identified 13 of the estimated 20 undeclared missile operating sites in November last year, which drew concerns among nuclear experts that the hermit country may not be winding down its nuclear arsenal.
"[We] have to negotiate [North Korea's] existing [nuclear] capabilities," Victor Cha, one of the authors of the report and senior adviser and Korean chair at the CSIS, urged on Twitter after its release. "Not just past [disclosed] or future ones."
