French President Emmanuel Macron tweeted an Islamophobic message Friday evening.
"We will not give up in the fight against Islamic terrorism," he wrote in a Twitter message, referring to an attack on a female police officer in a city near Paris on Friday.
The stabbing took place at the secure entrance to the police station in the commuter town of Rambouillet at 14:20 (12:20 GMT), BBC reported.
Witnesses said the attacker had been seen walking around while on his mobile phone outside the police station and seized his chance to go in as the woman - an unarmed administrative officer - went through the security doors.
He reportedly lunged at the officer, stabbing her in the neck. Her colleagues then opened fire on him.
Anti-terrorism prosecutors said they took over the investigation because of the way the attack had unfolded, remarks made by the attacker, and the fact that he targeted a police official.
