French police have shot dead a man who was apparently trying to attack a police station on the anniversary of the Charlie Hebdo attacks.
The suspect was carrying a meat cleaver and wearing a dummy suicide vest.
A piece of paper found on his body “pledged allegiance” to so-called Islamic State and vowed revenge for French “attacks in Syria”, AFP reported.
Officials have named him as a convicted thief, Sallah Ali, born in Morocco.
Minutes before he was shot, President Francois Hollande had praised police in a speech on last year’s killings.
Gunmen murdered 17 people in attacks, including at Charlie Hebdo magazine and a Jewish supermarket.
In his address, Mr Hollande said 5,000 extra police and gendarmes would be added to existing forces by 2017 in an “unprecedented” strengthening of French security.
he Paris prosecutor’s office says it is opening a terrorism investigation into the incident on Thursday, which took place in the 18th district in northern Paris.
French officials say the suspect, who was wielding the butcher’s knife, shouted “Allahu Akbar!” (God is Great) outside a police station in Goutte d’Or, near Montmartre, before police shot and killed him.
Bomb disposal experts were brought in after wires were seen extending from his body, but officials later said a belt he was wearing did not contain any explosives.
His fingerprints were found to match fingerprints on police files after an arrest for theft in the south of France in 2013.
Anti-terror police and French intelligence services are treating the incident as a case of attempted murder.
Following the attack, a cordon was been set up around the area, and security was boosted at schools and on public transport networks in the city.
