French officials say rioters burned cars and shot at police while protesting the police shooting of a man accused of robbing a casino.
The riot erupted late Friday night in the southeastern city of Grenoble.
Officials said the rioters also torched shops and attacked a streetcar (tramway) line. Police said some rioters also shot at officers and that they returned fire.
The French newspaper Le Monde says the youths started their rampage after hearing a Muslim imam give a ceremony for an alleged robber, who died Thursday night after being chased by police and exchanging gunfire.
