Iran has released on bail a U.S.-Iranian peace activist, Ali Shakeri, the last of four dual nationals to be freed after being detained on security-related charges, an Iranian news agency said on Tuesday.
Ali Shakeri, a founding board member of the Center for Citizen Peacebuilding at the University of California, was arrested in May at a Tehran airport as he was about to leave Iran. He was then transferred to Evin prison, rights groups say.
