DUBAI — Washington Post reporter Jason Rezaian went on trial on espionage charges behind closed doors in Tehran on Tuesday, 10 months after he was arrested at his home and imprisoned, Iran's semi-official Tasnim news agency reported. His wife Yeganeh Salehi and a woman described as a photojournalist, who were detained with him in July but later released, also went on trial, the official IRNA news agency said without giving any details on their charges. The three, all US-Iranian, were in court for around two hours before the session was adjourned, IRNA added. Iranian authorities have not released details of any charges and pressed on with the case in the face of calls from U.S. President Barack Obama, family members and rights groups for Rezaian's release and more information on the charges. — Reuters
