Iran's official IRNA news agency is reporting that a court has begun the third session in the trial of the detained Washington Post correspondent Jason Rezaian.

The Monday report did not elaborate.

Iran held two sessions for Rezaian in May and June in a Revolutionary Court on charges including espionage and distributing propaganda against the Islamic Republic. U.S. officials, the Post and rights groups have criticized his trial.

Rezaian, his wife and two photojournalists were detained on July 2014 in Tehran. All were later released except Rezaian, who has been held for over 300 days.

Rezaian is a dual U.S.-Iranian citizen who was born and spent most of his life in the United States. Iran does not recognize other nationalities for its citizens.
