A former U.S. Marine held in Iran describes the miserable prison conditions he has endured in a new letter to the U.S. secretary of state.
Amir Hekmati also says Tehran is holding him hostage for use in a possible prisoner exchange according the letter addressed to John Kerry and published by Britain's Guardian newspaper on Wednesday.
Family spokesman Greg Romano told The Associated Press on Wednesday that Hekmati's sister, Sarah (SAR'-uh), authenticated the letter. She says the handwriting is her brother's as is the letter's tone.
Romano says Amir Hekmati gave the letter to an unnamed person who then provided it to the Guardian.
Hekmati has been detained on what the U.S. says are false espionage charges. He grew up in Michigan.
