NKorea Nuclear, Missile Programs Making Progress A senior U.S. intelligence official and a report by a Washington-based research institute are warning of advances in North Korea`s nuclear and missile programs. Director of National Intelligence James Clapper said Wednesday Pyongyang has expanded the size of its Yongbyon uranium enrichment facility and restarted a reactor used for plutonium production. The statement appeared to confirm recent reports suggesting North Korea is making good on its promise to "adjust and alter" its nuclear facilities following its third nuclear test last year. In his written testimony to a Senate committee, Clapper also said the North`s nuclear weapons and missile programs "pose a serious threat" to the U.S. and Asia, noting that Pyongyang is committed to developing a missile that can strike the U.S. mainland. Clapper said that the North has publicly displayed its road-mobile intercontinental ballistic missiles, known as the KN-98, but stressed that the system remains untested. In a separate report Wednesday, the U.S.-Korea Institute at Johns Hopkins University said North Korea appears to be expanding its main launch site to accommodate larger missiles that could hit the U.S. The report, posted on the institute`s 38 North blog, said the Sohae Satellite Launching Station is undergoing modifications to enable it to launch rockets up to 25 percent longer than the Unha-3 space launch vehicle it tested in 2012. But the report, which relied on recent satellite photos, warned that because of ongoing construction the site will likely not be available for launches until March or April at the earliest. South Korea and the U.S. have been watching North Korea closely for a military provocation, such as a nuclear or missile test, following the shocking execution of Kim Jong Un`s uncle, who was accused of plotting to overthrow the state. Seoul`s Unification Ministry said Thursday it is "very serious and regrettable" that North Korea has made progress in its nuclear program, __________________________________________________________________ [1]http://www.voanews.com/content/nkorea-nuclear-missile-programs-makin g-progress/1840721.html References 1. http://www.voanews.com/content/nkorea-nuclear-missile-programs-making-progress/1840721.html
