AFP - French embassy staffer Nazak Afshar, on trial on charges related to post-election protests in Iran, has left the Tehran prison where she was being held, the French presidency said Tuesday.

President Nicolas Sarkozy repeated his call for French lecturer Clotilde Reiss, being held in the same prison, "to be freed without delay," it said in a statement.

Sarkozy spoke to Afshar, a French-Iranian dual national, after she was released, it added.

The president expressed his "gratitude to the countries of the European Union and to other friendly states, such as Syria, who gave us their support in this first phase," the statement said.

Reiss and Afshar were among defendants tried on charges related to huge protests across Iran after President Mahmoud Ahmadinejad was declared the winner of the June election.

The French government has denounced their trial as a travesty of justice and repeatedly demanded that the charges be dropped and the women released.

Ahmadinejad's main challenger Mir Hossein Mousavi alleged massive irregularities in the June 12 vote, triggering widespread protests in which about 30 people were killed, hundreds wounded and several thousand arrested.

Iran has put around 110 people in the dock over the protests.
