(AP Photo/IRIB) (Newser) – An American has been sentenced to death in Iran for spying for the CIA. Former US Marine Amir Mirzai Hekmati, 28, was convicted of "cooperating with a hostile nation." Hekmati, who also has Iranian citizenship, was shown on state TV last month confessing that he spied for the CIA. His confession was the key evidence against him, reports the Telegraph. His family in the US said he's no spy, and that he was in Iran visiting grandparents. The US State Department is demanding his release.
