Iran's official news agency says the country's judiciary expects to make a final decision in the case of three Americans charged with espionage by late August.

IRNA quotes Tehran's chief prosecutor Abbas Jafari Dowlatabadi as saying Tuesday the Americans' next court session is slated to be held between June 22 and August 22.

He says officials "are hopeful that the final decision about the three Americans' case will be taken at that session." He did not elaborate.

The three Americans -- Shane Bauer, Josh Fattal and Sarah Shourd -- were detained in July 2009 along the Iran-Iraq border.

Bauer and Fattal remain in custody. Bauer's fiancee, Shourd, was released last year on $500,000 bail and has refused to return to Iran for trial. The three deny the allegations.
