No sign of North Korea nuke reactor shutdown - U.S. official

News reports in South Korean media are "just not accurate ... We have seen no actions on the North Koreans' part that at this point leads us to believe they are fulfilling their part of the 60-day actions," said the official, who spoke on condition of anonymity. 

The official also said there was no indication the North had yet collected $25 million in accounts from a Macau bank that had been frozen as a result of U.S. action and then released as a way to persuade Pyongyang to return to negotiations over its nuclear program.
