French taxi drivers blocked Nice airport Tuesday over a dispute with online ride-hailing services, snarling traffic for hours as film-makers and movie moguls tried to reach the nearby Cannes film festival. Traffic in and out of the airport’s two terminals was disrupted and a woman taxi driver was knocked down, with the driver’s union threatening to stage another blockade on Friday. A police source told AFP tensions between the rival drivers traditionally escalate ahead of the world’s biggest film festival, which runs from May 14 to 26.
