Iran's Revolutionary Court sentenced an Iranian-US man to death for spying for the CIA, the semi-official Fars news agency reported on Monday.
"Amir Mirza Hekmati was sentenced to death ... for cooperating with the hostile country (the United States) and spying for the CIA," Fars said, without giving a source.
"The court found him Corrupt on Earth and Mohareb (waging war on God)."
Judiciary officials were not available for comment.
Hekmati, a 28-year-old of Iranian descent, was arrested in December and Iran's Intelligence Ministry accused him of receiving training at U.S. bases in neighbouring Afghanistan and Iraq.
Iran's judiciary said Hekmati admitted to having links with the CIA but said he had no intention of harming Iran.
