PARIS, March 11 -- A group of armed men attacked two armored vans transporting jewelry in southeastern Paris Tuesday night and looted 9 million euros (9.5 million U.S. dollars) worth of jewelry, according to local reports.

Fifteen masked men with automatic weapons held up two vans in the A6 motorway connecting Paris and Lyon, near Avallon tollgate and stole bags containing precious jewelry, the local broadcaster Europe1 said.

The perpetrators escaped in four cars and the two vans were found burned and abandoned in a forest near the site of the attack, an official said.

No shots were fired and no injuries were reported during the attack, according to the broadcaster. And the drivers of the two vans were left at the scene unharmed.

Gendarmes and other authorities are combing the Burgundy region southeast of Paris for the attackers, after the latest in a string of big jewel heists in France in recent years.
