Hopes raised for two Americans jailed in Tehran being freed

Morad Tahbaz and Siamak Namazi moved to cells where previously prisoners were held before release

Two high profile American-Iranian dual nationals detained in Tehran have been moved to a new location inside Evin prison in a procedure that has previously led to the release of detainees, according to sources inside the jail.

The moves could add credence to Iranian media reports at the weekend that a prisoner swap involving four unidentified detainees might be, or had been, imminent.
