Unions at France's main airport, Charles de Gaulle [controlled by Aéroports de Paris (ADP)]...have threatened to call a strike over alleged bias against Muslim workers. Seventy-two workers, mostly Muslims, have lost security clearance at the airport since May 2005...Some of them are suing the authorities, claiming they are being discriminated against because of their religion...Jacques Lebrot, the deputy prefect in charge of the airport, said security badges were withdrawn because the staff were "linked to fundamentalist movements with potentially terrorist aims".
