A controversial Iranian TV spy thriller is once again generating buzz in the Islamic Republic.

Newly filed court documents show that the FBI opened an investigation into Hekmati, on suspicions that he went to Iran to sell classified information to the regime. His lawyers say the government's suspicions, detailed in FBI documents and letters from the fund's special master denying payments, are groundless and based on hearsay. AdBut the FBI concluded that he went there intent on selling Iran classified information, according to an unsigned five-page summary of its investigation. Hekmati, the son of Iranian immigrants, says he researched Iran openly to cultivate an expertise on Iranian influence in Afghanistan. After Hekmati's lawyers warned they'd have to sue, the Justice Department cryptically indicated it was seeking a reconsideration of the award.

A U.N. panel has described an emerging pattern involving the arbitrary deprivation of liberty of dual nationals in Iran, which Tehran denies. The Thomson Reuters Foundation CEO, Antonio Zappulla, condemned the new charge, saying it would prolong Zaghari-Ratcliffes inhumane and unjust ordeal."
