There are reports of shots being fired on the Champs Elysee in the heart of the French capital, Paris, on Thursday evening.
French police are telling the people to avoid the area.
France remains tense after the government declared a state of emergency following a series of terrorist attacks, including the the November 2015 attacks, which targeted the Bataclan concert hall and Stade de France sports arena, as well as café and bar terraces in the capital.
The emergency decree has been extended by several parliamentary votes and remains in force.
