Iran's official IRNA news agency says the detained Washington Post correspondent is back in court for the second closed-door hearing in his espionage trial.

IRNA says Jason Rezaian's trial session started on Monday morning. The session is expected to last until early in the afternoon in Iran.

Rezaian, the Post's 39-year-old bureau chief, had his first closed-door hearing in May 26 in a Revolutionary Court on charges including espionage and propaganda against the Islamic Republic. U.S. officials, the Post and rights groups have criticized his trial.

Rezaian, his wife, Yeganeh Salehi, and two photojournalists were detained on July 22 in Tehran. All were later released except Rezaian.

IRNA says two other people detained with Rezaian are also on trial. It didn't elaborate or say if their hearing is in absentia.
