A teacher beheaded on a street near Paris on Friday afternoon has been named as Samuel Paty by French Education MinisterJean-Michel Blanquer.

The suspected killer, who officials said was an 18-year-old Chechen refugee, was armed with a knife and a plastic pellet gun, was later shot dead by officers in a nearby town, police said.

French authorities have launched an anti-terror investigation.

President Emmanuel Macron called it an "assassination" and an "Islamist terrorist attack".

Here's what we know about the attack so far:

Who was the victim?

Paty, a 47-year-old history and geography teacher, was decapitated near the school in the commune of Conflans Saint-Honorine, northwest of the French capital, at around 5 pm local time.

Police told the AFP news agency that he had hosted a class discussion with secondary school students about cartoons of Islam's Prophet Muhammad.

Some Muslim parents said they had complained to the school and French media reported Paty had received a number of threats in the wake of the class.

Blanquer said the school had taken "appropriate" steps in response to the complaints in setting up measures that both "supported the teacher and opened up a dialogue with parents".

The minister added he would prepare a pedagogical "framework" on how to address the attack with students when they returned to school after half term. He said a minute's silence would be organised.

President Emmanuel Macron visited the Bois d'Aulne school and met the history teacher's colleagues on Friday evening.

He said afterwards: "One of our citizens was assassinated tonight because he was a teacher, because he taught students about the liberty of expression, the liberty to believe or not to believe.

"Our countryman was the victim of a cowardly attack. The victim of an Islamist terrorist attack."

Who was the alleged perpetrator?

His alleged attacker was reported to be 18 years old, of Chechen origin and born in Moscow.

Officials said he was shot dead in the neighbouring town of Éragny after he acted in a threatening manner and failed to respond to an order to put down his weapons.

Officials said he was unknown to intelligence services.

French anti-terrorism prosecutor Jean-Francois Ricard told reporters the suspect, who had been granted a 10-year residency in France as a refugee in March, was armed with a knife and an airsoft gun, which fires plastic pellets.

His half-sister joined the Islamic State group in Syria in 2014, Ricard said. He didn't give her name, and it is not clear where she is now.

The prosecutor said a text claiming responsibility and a photograph of the victim were found on the suspect's phone.

He also confirmed that a Twitter account under the name Abdoulakh A belonged to the suspect. It posted a photo of the decapitated head minutes after the attack along with the message “I have executed one of the dogs from hell who dared to put Muhammad down.”
