Prominent trade union Workers' Force identified the two Thursday as a teachers' union official named Cecile Kohler and her partner. They were on a tourist trip to Iran as part of an Easter vacation break. The union said it was made aware of the arrests Wednesday. France's Foreign Ministry said its ambassador in Tehran has already attempted to obtain consular access to the couple. The charge d'affaires at Iran's Paris embassy have been summoned for explanations. The ministry didn't say what charges the two French faced.
