US diplomat returns from N. Korea with boxes of nuclear records

A US diplomat left North Korea on Saturday with boxes of documents detailing activities at the nuclear reactor that is at the heart of the communist country's nuclear weapons program. Washington plans to scrutinize the technical logs from the Yongbyon reactor to see if the North is telling the truth about a bomb program that it has agreed to trade away for economic and political rewards. Sung Kim, the US State Department's top Korea specialist, returned to South Korea by land across the heavily fortified border after collecting approximately 18,000 secret papers during a three-day visit to Pyongyang.
