North Korea has a secret military base near its border with China, which could pose a “potential nuclear threat” to much of East Asia and the US. According to a CSIS report, the secret military base near northern China may house Pyongyang’s newest long-range ballistic missiles. North Korea’s “undeclared” Sinpung-dong missile operating base lies about 27 km from the Chinese frontier, the research claims. The facility in North Pyongan province likely houses six to nine nuclear-capable intercontinental ballistic missiles (ICBMs) and their launchers, the study claims. CSIS researchers believe the base is equipped with North Korea’s nuclear-capable Hwasong-15 or Hwasong-18 ICBMs, or another “undeclared” type of ICBM. Video: AFP/Reutersn18oc_world n18oc_crux
