PARIS - President Emmanuel Macron urged calm after 150 people were arrested and public buildings were attacked in angry protests over the police killing of a teenager that has incensed France.
Nahel M. was shot in the chest at point-blank range on Tuesday in an incident that has reignited debate in France about police tactics long criticised by rights groups.
Cars and bins were torched in parts of Paris overnight and protesters launched fireworks at riot police, who fired flashball projectiles to try to disperse the angry crowds.
"We are sick of being treated like this. This is for Nahel, we are Nahel," said two young men calling themselves "Avengers" as they wheeled rubbish bins from a nearby estate to add to a burning barricade in the capital.
As the situation has grown more volatile, Macron called an early morning crisis meeting of his ministers.
Branding the overnight clashes "unjustifiable", Macron told the meeting the "last few hours have been marked by scenes of violence against police stations, but also schools and town halls... against institutions and the Republic."
Interior Minister Gerald Darmanin wrote on Twitter as he announced the 150 arrests figure that the violence was "intolerable".
He expressed support for police but added in an apparent swipe at the hard-left: "Shame on those who did not call for calm."
In the region around the scene of Nahel M.'s killing, masked demonstrators dressed in black launched fireworks and firecrackers at security forces.
A thick column of smoke billowed above the area where AFP journalists saw more than a dozen cars and garbage cans set ablaze and barriers blocking off roads.
Graffiti sprayed on the walls of one building called for "justice for Nahel" and said, "police kill".
In the working-class 18th and 19th districts of northeastern Paris, police fired flash balls to disperse protesters burning rubbish, but instead of leaving, the crowd responded by throwing bottles.
In the Essonne region south of the capital, a group set a bus on fire after forcing all the passengers off, police said, while in the Paris suburb of Clamart a tram was set on fire.
In the southern city of Toulouse, several cars were torched and responding police and firefighters pelted with projectiles, a police source said, while authorities reported similar scenes in Dijon and Lyon.
