France will ramp up security to protect the public during voting in the French presidential elections in the wake of the Champs-Élysées attack.
French Prime Minister Bernard Cazeneuve said nothing will stop Sunday's elections as he confirmed the government had fully mobilised its security forces, including elite units, to bolster the 50,000 police already on duty.
Thursday evening's fatal shooting of a policeman in Paris came with only days to go until Sunday's national poll - the first round of the two-round election.
Two officers injured by an armed attacker are both out of danger, French officials said.
Interior Ministry spokesman Pierre-Henry Brandet said one of the injured officers was more gravely hurt than the other but both are doing better.
Prosecutors describe French national with a long history of violence and criminal offences but few obvious signs of radicalisation.
A police officer has been killed and two others wounded in a shooting in the centre of Paris - here's what we know so far.
