None
Longstanding US concerns about North Korea's uranium enrichment program have been confirmed by a US nuclear scientist's recent visit to the reclusive state, the top US military officer said on Sunday.
North Korean officials took the expert, Siegfried Hecker of Stanford University, to a plant at its Yongbyon nuclear complex where he saw hundreds of centrifuges, sources familiar with the matter told Reuters on Saturday. (Reuters)
