A man was beheaded near a school in a Paris suburb on Friday by an attacker suspected of being an Islamist terrorist heard shouting "Allah Akbar", police said.
The attack happened at around 5 pm (1500 GMT) near a school in Conflans Saint-Honorine, a western suburb of the French capital.
Officers saw a man with a knife in the area shortly after the attack. The police shot the suspect dead, according to a police spokesman.
The investigation is being directed by specialised anti-terrorism prosecutors.
Interior Minister Gerald Darmanin, on a visit to Morocco, is returning to Paris immediately after talking with Prime Minister Jean Castex and President Emmanuel Macron, his office said. The police spokesman said that information was being checked.
The report also added the attacker was the parent of a student, but this has not yet been confirmed by police.
Charlie Hebdo itself had been the site of an attack in January 2015, which resulted in a dozen dead and nearly as many injured after two gunmen entered the offices following the publication of a cartoon depicting the prophet Mohammed.
This had been in retribution for the magazine's publication of cartoons of the Prophet Mohammad.
This is a breaking story.
