A driver who attacked police on Paris's Champs-Elysees on Monday was a 31-year-old man who had been on a security watchlist since 2015 for membership of "the radical Islamist movement," sources close to the probe said.

The man died after ramming a car into a police van on the prestigious avenue. Police sources told AFP that a Kalashnikov assault rifle, handguns and gas canisters were found in the vehicle.
