Tension simmers in French suburbs

By James Mackenzie

VILLIERS-LE-BEL, France (Reuters) - Youths in Paris suburbs and the city of Toulouse torched cars and set rubbish ablaze in fresh urban violence in France on Tuesday.

With police out in force, the situation remained tense.

But there were only isolated incidents of vandalism and officials reported no major clashes between youths and police in contrast to Monday night when around 80 police officers were injured when rioters pelted them with stones and petrol bombs.

"(The situation) is much calmer than in previous nights but you can feel all this remains fragile," Prime Minister Francois Fillon said after meeting officials in the northern Paris suburb of Villiers-le-Bel, where unrest erupted on Sunday.

The government pledged to take a firm line against rioters who attacked police, and there was a heavy police presence in Paris suburbs. Officers in riot gear and dozens of police vans lined the main street of Villiers-le-Bel, as a helicopter circled above.

Around a dozen cars were set ablaze in suburbs in Paris.

In Toulouse in the south vandals torched about 20 cars, police said. They also tried to set fire to a library in a working class district of the city, but police said they stepped in before there was any real damage.

The urban unrest, triggered by the deaths of two youths who were on a moped that collided with a police car, have posed a fresh challenge to the leadership of President Nicolas Sarkozy after transport strikes and student protests over his reforms.
