S. Korea: North may be readying for UN inspectors

North Korea may be preparing to invite UN inspectors to discuss shutting down its main nuclear reactor, South Korea's spy agency said Thursday. North Korea has constructed a small building near the Yongbyon reactor and repaired a road leading to it, the National Intelligence Service said in a report to the parliament's intelligence committee. The building is believed to be a "convenience facility" for inspectors from the International Atomic Energy Agency, the UN nuclear watchdog, according to the report released by the parliamentary committee. Piles of unidentified objects were also seen near the nuclear waste storage facility in the complex and ground-leveling activity was also detected, the report said, without elaborating.
