Iranian state television has aired a video showing what it says is an Iranian nuclear scientist. The video allegedly shows Shahram Amiri, a university researcher working for Iran’s Atomic Energy Organization who disappeared during a pilgrimage to Saudi Arabia a year ago. In the video, Amiri claims he had been kidnapped and taken to the United States where he was tortured. Iranian television said the video had been passed to members of the country’s intelligence agency, but did not give details of how this was done. In March, ABC News said Amiri had defected to the United States and was helping the CIA.
