North Korea Movements at Nuclear Site Spark Speculation of Test Movements of North Korean personnel and vehicles near an atomic weapons site are sparking speculation of a third nuclear test as leader Kim Jong Il prepares to hand over power to his youngest son. A U.S. reconnaissance satellite has detected movements at Punggyeri in North Koreaâ€™s northeastern North Hamgyong Province that may be related to preparations for a third nuclear test, Chosun Ilbo newspaper reported today, citing a South Korean government official it didnâ€™t identify. It may take about three months for the North to conduct a test blast, the report said. South Koreaâ€™s military is carefully monitoring the site, where activities have commonly been detected, a defense ministry official said in Seoul on condition of anonymity according to ministry policy. The official declined to say whether there have been any abnormal movements in the area to suggest an imminent nuclear test. Yonhap News and KBS television reported today that there hasnâ€™t been any indication of a nuclear test, both citing South Korean government officials they didnâ€™t identify. North Korea conducted its second nuclear test in May 2009 after the first blast in October 2006, prompting the United Nations Security Council to toughen sanctions. The country may be seeking to showcase bolstered military capability to rally support for Kimâ€™s youngest son and heir-apparent, Kim Jong Un, Chosun said. Promotion to General Kim Jong Un was made a general and appointed to a post in the ruling Workersâ€™ Party of Korea last month, setting the stage for a hereditary power transfer. The six-party talks on ending the Northâ€™s nuclear weapons program last met in December 2008. The arms negotiations also involve China, Japan, Russia, South Korea and the U.S. The speculation of North Koreaâ€™s nuclear test comes as South Korea is preparing for the Group of 20 leadersâ€™ summit in Seoul next month. South Korea has said the nation is on alert for possible North Korean provocations including explosions at â€œmajor facilities,â€ suicide bombings, chemical assaults or cyber attacks during the Nov. 11-12 meetings. South Korea remains technically at war with North Korea since their 1950-53 conflict ended in a cease-fire, which was never replaced by a peace treaty. Kim Jong Ilâ€™s regime is accused of torpedoing a South Korean warship in March, killing 46 sailors.
