PARIS, Nov. 3 - Angry youths clashed with police and firefighters outside Paris late Wednesday in the worst of seven straight nights of violence set off by the accidental death of two teenagers. By late Thursday, more cars were burning in at least one of the city's northern suburbs.Gunshots were fired at police officers and firefighters in three separate incidents Wednesday night, said Prefect Jean-François Cordet, the government's top official in Seine-St.-Denis, a department north of Paris that includes a belt of working-class neighborhoods with a large immigrant population from North Africa and the sub-Saharan region.In the clashes on Wednesday night, a police station was ransacked, a garage was set on fire and a shopping center and two schools were vandalized, Mr. Cordet said. Riot police forces have used tear gas and rubber bullets to repel the attacks.Traffic was halted Thursday morning on a commuter line linking Paris to Charles de Gaulle airport after stone-throwing rioters attacked two trains. One passenger was slightly injured by broken glass, according to local news reports. The violence picked up again as night fell with burning cars reported in the suburb of Stains.
