North Korea is upgrading its only known nuclear research facility, satellite imagery has shown, despite ongoing negotiations with multiple world leaders and a pledge to abandon its weapons program. The satellite photos, obtained by North Korea analysis outlet 38 North, indicate that the isolated regime is making numerous improvements to its Yongbyon Nuclear Scientific Research Center “at a rapid pace.” The report comes just over two weeks after President Donald Trump and North Korean leader Kim Jong Un signed an agreement that called for a denuclearized Korean peninsula.

38 North is a U.S.-based project that looks to gather the insight of several long-time observers of North Korea. The site, which is perhaps best known for its monitoring of Pyongyang’s nuclear weapons program, is affiliated with experts at both the Stimson Center and non-profit Foreign Policy Research Institute.
