Reuters stated this in an article, citing the Paris prosecutor's office, Ukrinform reports.
According to the report, the prosecutor's office identified one of the individuals as Anna N, a dual French-Russian national who has been under the surveillance of France's DGSI domestic intelligence agency since January on the belief she was gathering intelligence.
"In particular, she was suspected of having approached executives of various French companies in order to obtain information relating to French economic interests," the prosecutor said in a statement.
The others were identified as Vincent P and Bernard F, who were born in France and Vyacheslav P, a Russian national.
According to the prosecutor's office, Anna N founded SOS Donbass, a France-based association which says on its website that it campaigns for closer ties between Europe and Russia, and the end of arms deliveries to Ukraine. It often displays campaign posters in public places.
