Police have shot dead a man minutes after he slit a history teacher’s throat near a school in a suburb of Paris.
France’s anti-terror prosecutor said it was investigating the attack, which took place in the north-west neighbourhood of Conflans Sainte-Honorine.
The teacher had opened up a discussion with students on caricatures of Islam’s Prophet Muhammad before his death, a police official said.
The suspected attacker was spotted by a police patrol while carrying a knife a short distance from the scene of the attack.
A police source said that witnesses had heard the attacker shout ‘Allahu Akbar’, or ‘God is Great’.
It comes almost a month after two people were attacked with a meat cleaver outside the former Paris offices of Charlie Hebdo.
The magazine has been operating in a secret location ever since extremists massacred 12 people in 2015, over the publishing of controversial cartoons of the Prophet Muhammad.
