The gunman who shot dead a policeman in Paris on Thursday has been identified from papers left in his car, but French officials are yet to release his name.
Local media say the 39-year-old lived in the city’s suburbs, and had been seen as a potential Islamist radical.
The gunman also wounded two police officers before he was killed by security forces on the Champs-Elysees.
President François Hollande is to chair a security cabinet meeting, as France readies for Sunday’s presidential poll.
Mr Hollande said he was convinced the attack was “terrorist-related”, adding that the security forces had the full support of the nation and a national tribute would be paid to the fallen policeman.
So-called Islamic State (IS) said one of its “fighters” had carried out the attack.
