Syria said UN nuclear inspectors could not make a return visit to a suspect site bombed by Israeli jets last year because its agreement with the UN agency allowed only one trip. A Foreign Ministry official said Syria had told the International Atomic Energy Agency that it was ready to answer any questions. Diplomats told the Associated Press in Vienna, where the agency is headquartered, that Syria had blocked a new visit to follow up on a June trip. The US alleges that the remote site was a near-finished plutonium-producing reactor built with North Korean help and that Damascus is hiding linked facilities. The Syrian official denied that, speaking Saturday on condition of anonymity as the official was not authorized to speak to media.
