TEHRAN, Iran -

 Iran's state radio says a court has convicted a Michigan man of working for the CIA and sentenced him to death.

Monday's report said Amir Mirzaei Hekmati was also convicted of trying to accuse Iran of involvement in terrorism.

The report didn't say when the verdict was issued. Under Iranian law, he has 20 days to appeal.

Iran charges that as a former U.S. Marine, Hekmati received special training and served at U.S. military bases in Iraq and Afghanistan before heading to Iran for his alleged intelligence mission.

His father, a professor at a community college in Flint, Mich., has said his son is not a CIA spy and was visiting his grandmothers in Iran when he was arrested.

The 28-year-old was born in Arizona and graduated from high school in Michigan. His family is of Iranian origin.
