The lawyer of Washington Post reporter Jason Rezaian says her client will appear in court Monday, likely for the last hearing in his closed-door espionage trial in Iran.

Leila Ahsan told The Associated Press on Saturday that Monday's court session will be devoted to her defense of Rezaian, the Post's Tehran bureau chief.

Rezaian, held for more than a year, reportedly faces up to 10 to 20 years in prison if convicted in Tehran's Revolutionary Court on charges that include espionage and distributing propaganda against the Islamic Republic. The Post, the U.S. government and press freedom organizations have criticized his trial.

Rezaian is an Iranian-American who holds dual citizenship, which Iran doesn't recognize.

Rezaian, his wife and two photojournalists were detained on July 2014. All were later released except Rezaian.
