France lashed out at Iran for "dictatorial practices" and taking two of its citizens hostage after a video aired on Thursday in which they appeared to confess to spying.
Iran's intelligence ministry said in May it had arrested two Europeans for allegedly fomenting "insecurity" in Iran. France has condemned their arrest and demanded the immediate release of Cecile Kohler and her partner Jacques Paris.
Iran’s state media often air purported confessions by suspects in politically charged cases.
"I am Cecile Kohler, I am an intelligence and operations agent at the DGSE (Directorate General for External Security) ... We were in Iran to prepare the ground for the revolution and the overthrow of the regime of Islamic Iran," Kohler said in the video, while wearing a headscarf, referring to the French external intelligence service.
The video sparked outrage in Paris with Foreign ministry spokeswoman Anne-Claire Legendre saying for the first time that the two citizens, along with two others also being held in Iran, were "state hostages".
"The staging of their alleged confessions is outrageous, appalling, unacceptable and contrary to international law. This masquerade reveals the contempt for human dignity that characterizes the Iranian authorities," Legendre said.
"These alleged confessions extracted under duress have no basis, nor did the reasons given for their arbitrary arrest. State TV said the French couple had entered Iran with "chunks of money ... which was meant to fund strikes and demonstrations."
"Our goal at the French security service is to pressure the government of Iran," said Jacques Paris in the video.
The French couple's appearance on TV coincides with weeks of anti-government protests in Iran over the death of 22-year-old Mahsa Amini in police custody last month. It also comes a day after a debate in the French senate in which all political parties condemned Iran's crackdown and backed the government to toughen its stance on Tehran.
