Shots have been fired at a new location near the Champs Elysees in Paris, according to a report.
Earlier on Thursday night a police officer was killed and another injured on the popular avenue.
Reuters reported a police source as saying gunfire was reported at a separate location.
The French Interior Ministry said the shooting attack on the famed deliberately targeted police officers guarding the area.
Ministry spokesman Pierre-Henry Brandet said on BFM television that a man came out of a car and opened fire on a police vehicle.
One officer was killed and another was wounded.
The police counter-terrorism office has opened an investigation into the shooting, the prosecutor's office said. One of the gunmen was killed and a police source said that the attacker was known to security seervices.
Mr Brandet said the police officers were “deliberately” targeted.
He said police are securing the area but there is “no other police operation underway” in the popular area.
Brandet says it was too early to say whether the attacker might have had an accomplice, and said authorities are studying multiple potential motives.
Speaking in Washington during a news conference with Italian Prime Minister Paolo Gentiloni, US President Donald Trump said the shooting “looks like another terrorist attack” and sent condolences to France.
