"On October 9, 2006, North Korea announced it conducted a nuclear test. It is not yet clear whether North Korea achieved a nuclear yield and if so, how big. North Korea ended an eight-year freeze on its plutonium production program in 2002, expelling international inspectors and restarting facilities. Whereas many believed North Korea might have had enough plutonium (Pu) for one or two weapons in then, North Korea may now have enough Pu for six or eight more weapons. In 2005, North Korea announced it had nuclear weapons, but rejoined the Six-Party Talks in July and agreed to abandon its nuclear weapons program in September 2005. The failure of the talks has allowed North Korea to continue to produce fissile material for nuclear weapons. The United States and other countries have condemned the North Korean nuclear test and called for sanctions. This report will be updated as needed."
