Riots in France expose unresolved tensions since 2005

Rampaging youths threw Molotov cocktails and set fire to dozens of cars in troubled neighbourhoods outside Paris during a second night of street violence after two local teens were killed in a crash with a police patrol car.

President Nicolas Sarkozy, visiting China, appealed for calm on Monday, while police braced for more problems. With several dozen officers injured during two nights of rioting, the violence was a reminder of the tensions that drove weeks of rioting in 2005 in poor neighbourhoods with large minority populations.
