Paris police and soldiers have sealed off the area around the Champs-Elysees after an attack on police, ordering tourists back into their hotels and blocking people from approaching the scene.
Emergency vehicles blocked the wide avenue that cuts across central Paris between the Arc de Triomphe and the Tuileries Gardens, normally packed with cars and tourists.
Subway stations in the area were closed off on Thursday night while police secure the scene.
Security forces are more widespread in Paris since deadly Islamic extremist attacks in recent years, and France remains under a state of emergency.
