Truck attacker kills dozens in Nice, driver shot dead

At least 50 people were killed and 100 injured in the French Riviera city of Nice late on Thursday when a truck ploughed into crowds watching a fireworks display on France's Bastille Day national holiday in a criminal attack, a local official said.

The driver, who drove at high speed for over 100 meters (yards) along the famed Promenade des Anglais seafront before hitting the mass of spectators, was shot dead, sub-prefect Sebastien Humbert told France Infos radio.

Humbert described it as a clear criminal attack, although the driver was not yet identified. Residents of the Mediterranean city close to the Italian border were advised to stay indoors. There was no sign of any other attack.

Almost exactly eight months ago Islamic State militants killed 130 people in Paris. On Sunday, France had breathed a sigh of relief as the month-long Euro 2016 soccer tournament ended without a feared attack.

"Dear Nicois," local mayor Christian Estrosi tweeted, "The driver of a truck appears to have killed dozens of people. Stay at home for the time being. More news to follow."
