April 08, 2012 News Report Says North Korea Preparing for Third Nuclear Test VOA News Map of North Korea South Korea's semi-official Yonhap news agency reported Sunday that North Korea appears to be preparing for a third nuclear weapons test. The report quoted an unidentified intelligence source as saying that satellite images show workers at the Punggye-ri nuclear test site in the northeast digging a new tunnel. The North conducted two previous nuclear tests at the site, first in October of 2006 and again in May of 2009. The source told Yonhap that it appears the mining work is in its final stage. North Korea agreed in February to stop nuclear tests, uranium enrichment and long-range missile launches in return for food aid. But that agreement unraveled when Pyongyang announced in March that it plans to launch a satellite into space this month. Pyongyang insists the launch is a peaceful space project, but countries including the United States, Japan and South Korea view it as a disguised missile test, in breach of UN resolutions. Some information for this report was provided by AFP and Reuters. .
