Iran's official news agency is quoting a prosecutor saying a detained Washington Post journalist has been indicted and will stand trial.

The official IRNA news agency quoted Tehran prosecutor Abbas Jafari Dowlatabadi on Wednesday saying that Jason Rezaian, the newspaper's bureau chief in Tehran since 2012, had been indicted. He is an Iranian-American who holds dual citizenship.

Rezaian has been held since July 22. The IRNA report did not disclose what charges he faces. However, the report says he will stand trial in Iran's Revolutionary Court, which mostly hears cases involving security offenses.
