France said on 8 November that one of its citizens being held in Iran has been sentenced to five years in prison on a baseless conviction, and called for his immediate release and that of three other of its nationals held in the country. Ties between the two countries have been strained over the issue in what Paris has said are arbitrary arrests that are equivalent to state hostage taking. Louis Arnaud, who has been held since September 2022, is being detained at the Evin prison in Tehran. His mother said that the pretexts given for his sentencing were for propaganda and harming the security of the Iranian state: ‘These are completely baseless, a carbon copy of what they attribute to other Europeans held in Iran.’ In recent years, the elite Revolutionary Guards have arrested dozens of dual nationals and foreigners, mostly on charges related to espionage and security. Rights groups have accused Iran of trying to extract concessions from other countries through such arrests - a charge which the government denies.
