Never work for the CIA, they will betray you…
The scientist claiming to have been kidnapped and tortured by the United States was a CIA mole who spied on Iran's nuclear programme for several years, American officials have said.
Shahram Amiri was a vital source whose "significant, original" intelligence allowed his US minders to build up a comprehensive assessment of Iran's clandestine nuclear capabilities, the officials claimed.
The allegations are the latest twist in an increasingly perplexing saga that has embarrassed the United States and prompted jubilant crowing in Iran, which has long maintained that the CIA kidnapped Mr Amiri during a visit to Saudi Arabia last year.
Mr Amiri was reunited with his wife and seven-year-old-son after flying back to a hero's welcome in Iran on Thursday. He repeated allegations that he had been abducted, tortured by Israeli and American officers, and later offered $10 million (£6.5 million) to say that he had come to the United States of his own volition
