A French-Iranian anthropologist who Iran has detained for nearly a year now must serve six years in prison on national security charges

Fariba Adelkhah, 60, was sentenced to five years for gathering and conspiring against Iran’s national security and one year for “propaganda against the Islamic Republic,” her lawyer, Saeid Dehghan, told Reuters. He plans an appeal.

France is demanding Adelkhah’s immediate release, calling her conviction politically motivated; Iran has rejected France’s call as an interference into Tehran’s internal affairs.

Iran freed Adelkhah’s partner, French academic Roland Marchal, in March after France released Iranian engineer Jalal Ruhollahnejad, who had been arrested there on suspicion of violating US sanctions against Iran.

French officials had agreed to extradite Ruhollahnejad to the U.S. last May to face charges of illegally importing U.S. technology for military use on behalf of an Iranian company allegedly linked to Iran’s elite Revolutionary Guard.

The Trump administration harshly criticized France’s decision to swap Ruhollahnejad for Marchal.
