Gangs of youths torched 1,300 vehicles overnight in the 10th consecutive night of violence in Paris' poor suburbs and major French towns, despite the deployment of thousands of extra police.

Cars were burned out in the historic centre of Paris for the first time on Saturday night. In the normally quiet Normandy town of Evreux, a shopping mall, 50 vehicles, a post office and two schools went up in flames.

Authorities have so far found no way beyond appeals and more police to address a problem with complex social, economic and racial causes.

Evreux mayor Jean-Louis Debre, a confidant of President Jacques Chirac and speaker of the lower house of parliament, told France Info radio:

"To those responsible for the violence, I want to say: Be serious ... If you want to live in a fairer, more fraternal society, this is not how to go about it."

Authorities now say the rolling nightly riots are being organized via the Internet and mobile phones, and have pointed the finger at drug traffickers and Muslim militants. Overnight, police made 349 arrests. The number of incidents in the Paris region was similar to the night before, but in the provinces it was up sharply.

Prime Minister Dominique de Villepin has combined a call for an end to the riots with dialogue with community leaders, youngsters and local officials, and has promised an action plan for 750 tough neighbourhoods.

"I'll make proposals as early as this week," the weekly Journal du Dimanche quoted him as saying.

But it remained unclear what could stop the violence, though some opposition parties have suggested a symbolic measure the resignation of Interior Minister Nicolas Sarkozy.

Accused of stoking passions by calling troublemakers "scum", Sarkozy has ignored calls to quit. A survey published Sunday indicated his public image was holding up, even if many disapproved of his strong language.
