French police opened fire Sunday at a car which smashed through a security barrier in central Paris close to the finishing line of cycling's Tour de France, a police source said.

The authorities were still searching for the driver after the incident which happened at around 8:00 am (0600 GMT) at the Place de Concorde at the end of the famous Champs Elysees, where the world's greatest cycling race is to finish later Sunday.
