French Foreign Minister Jean-Yves Le Drian on Friday reiterated his demands for Iran to release French-Iranian academic Fariba Adelkhah, whom Iran has sentenced to six years in prison on national security charges. 'Today, I once again formally demand on behalf of France the immediate liberation by Iran of Madame Adelkhah,' Le Drian said in a statement. 'This ongoing situation can only have a negative impact on the bilateral relations between France and Iran, and can only significantly reduce the trust between our two countries,' he said.
