France President Emmanuel Macron has accused protesters of exploiting the death of a teenager shot by police at point-blank range.
At a crisis meeting, the president said more officers would be deployed to contain the violence, but stopped short of declaring a state of emergency.
He urged parents to keep rioting children at home and social media platforms to remove certain content.
France has been rocked by three nights of unrest after 17 year old Nahel was killed as he drove away from a traffic stop.
More than 915 arrests were made on Thursday night alone and the government announced it would deploy 45,000 police officers in a bid to contain further violence.
Imploring parents to take action, he said it was their “responsibility” to keep any child intending to protest “at home”.
Mr Macron condemned the violence of the last three days “with the greatest firmness” and said Nahel’s death had been used to justify acts of violence – calling it an “unacceptable exploitation of the adolescent’s death”.
