An Iranian court threw out a 2011 death sentence for Amir Hekmati, a former U.S. Marine charged with spying. But he was secretly retried in Iran and convicted of "practical collaboration with the U.S. government," his sister told CNN on Friday, April 11. He has been sentenced to 10 years in prison, she said. Hekmati was detained in August 2011 during a visit to see his grandmother. His family and the Obama administration deny accusations he was spying for the CIA.
