> A secret North Korean nuclear site may have been found. US think tank The Institute for Science and International Security says it's located a facility that was likely used in the early days of North Korea's atomic program, playing a key role in enriching weapons grade uranium.
The report says there's always been doubt about whether North Korea has disclosed all its nuclear facilities. If the site is confirmed, it will be critical to any future deal to freeze and dismantle Pyongyang's nuclear production line. The small scale operation is believed to sit inside an aircraft part factory within a mountain, that matches reports in a Japanese newspaper from 16 years ago that described a similar undeclared facility.
North Korea has declared it has one uranium enrichment plant at its current nuclear plant but denies having any others. It's not clear whether the possible plant is operational, but according to North Korean defectors, sources inside the country say there could be up to three plants up and running.
