Today, Tuesday, Iran revealed the details of the arrest of two French citizens earlier this month in Tehran on charges of "seeking to stir unrest" by meeting representatives of the Iranian teachers' unions.

Iranian TV reported that the detainees entered Iran on a tourist visa from Turkey on April 28.

He said that they were working to destabilize security and stir unrest in Iran by infiltrating teacher protests in the country recently.

He explained that the detainees are Cecil Kohler (37 years) and her partner Jacques Paris (69 years), adding that "the two spies were intending to stir up unrest in Iran by organizing union protests."

The footage showed what the television said was their arrival at the "Imam Khomeini International Airport" in Tehran on April 28 from Turkey on a Turkish Airlines plane, as well as their arrest on their way to the airport on May 7.

On May 11, the Iranian Ministry of Intelligence said that it had arrested two Europeans for allegedly "undermining security" in Iran, but did not reveal their nationalities.

Christophe Lalonde, Federal Secretary of France's National Confederation of Education, Culture and Vocational Training, said on May 12 that he suspected that a female federation worker and her husband, missing while on vacation in Iran, had been arrested by Iran.

While the Iranian judiciary has not commented on the matter yet, France condemned their detention as baseless and called for their immediate release.

The incident is likely to complicate relations between the two countries as broader talks on reviving the nuclear deal have stalled.

It is noteworthy that human rights groups accuse Iran of trying to extract concessions from other countries through such arrests, but Tehran always denies these accusations.
