North Korea has secret nuclear sites: UN report:
"North Korea has at least one secret nuclear military facility, a panel of experts has told the UN Security Council in a report calling for tougher implementation of sanctions, diplomats said Monday.
The subterfuge work was probably started in the 1990s without raising suspicions, according to diplomats who have seen the report which could be discussed by a special Security Council sanctions committee in coming days.
The report is based on evidence from US scientist Siegfried Hecker who was taken to a secret site by the North Korean authorities last November."
