I am getting e-mail reports from Kabul and Washington that Kian Tajbakhsh has been released on bail from Evin Prison, and that Parnaz Azima has been issued a passport and will soon leave Iran. I will post again if there is any confirmation.
Update: RFE/RL confirms the news about Azima.
Further Update: BBC Persian Service reports that the spokesman of the national security court stated on Iran state television that the investigation of Kian's the case is continuing (dar juryan ast), but that he will be released on bail when the investigation is concluded. As far as I can see there is no date given.
