From news article:
November 21, 2011: South Korean intelligence has revealed that there are several hundred North Korean scientists, engineers and technicians working in Iran's nuclear weapons program. The North Koreans work at ten locations, and are regularly rotated back to North Korea and replaced. Such a North Korean presence has long been known, but was believed for the ballistic missile program. Now, there are accusations of extensive North Korean help with Iran's nuclear weapons program. Earlier this month, the UN IAEA (International Atomic Energy Agency) issued a report that accused Iran of having a nuclear weapons program. The report provided lots of details. Russia, China and other Iran allies tried to block release of the report, but without much success. The report describes a nuclear weapons research facility outside Tehran, and the use of computer simulation to guide the nuclear weapon design process. IAEA believes Iran now has enough enriched (to weapons grade) uranium for three nuclear weapons, but is still encountering technical problems in producing a workable weapon.
