A man armed with a knife on Friday killed a middle school history teacher by slitting his throat in front of his school in a suburb of Paris, police said, in an attack that was being treated as terrorism.
The attacker was shot dead by a police patrol a few streets away. The teacher had shown pupils in his class cartoons of the Prophet Mohammad, which are considered by Muslims to be blasphemous, according to a police source.
France's anti-terror prosecutor said it was investigating the attack, which took place in Conflans Sainte-Honorine, a commuter suburb north-west of Paris. President Emmanuel Macron arrived at the scene on Friday evening.
French broadcaster BFMTV reported that the suspected attacker was 18 years old and born in Moscow.
