A Franco-Iranian academic has been arrested in Iran and denied access to consular staff, the French Foreign Ministry said Monday.
Fariba Adelkhah, an anthropologist at the French university Sciences Po, was arrested for allegedly spying , according to Iranian media outlets. Separately, the Reuters news agency reports she was arrested in June.
"The French authorities in this difficult context have taken steps with Iranian authorities to get information from them on her situation and the conditions of her arrest and asked for consular access as is foreseen in these circumstances, necessary precursor for her quick release," Foreign Ministry spokeswoman Agnes von der Muhll said in a statement.
"No satisfactory response has been given to these requests. France calls on the Iranian authorities to bring to light Mrs. Adelkhah's situation and reiterates its requests, in particular the authorization of consular access without delay," she also said.
Iranian officials have not confirmed the charges.
The arrest comes as many European nations seek to de-escalate tensions, following the United States' withdrawal from a 2015 international Iran nuclear deal.
