Jewish-owned businesses and a synagogue were targeted in the suburb of Sarcelles, just outside Paris.
Shops were looted and 18 people were arrested as youths went on the rampage during Sunday's protest, which had been banned by authorities.
The mayor of Sarcelles said the Jewish community was in fear.
Such an outpouring of violence had never been seen in the suburb before, he said.
Roger Cukierman, head of the umbrella group Crif that represents French Jewish organisations, said Jews were not just afraid, they were anguished.
"What's happened in the past few days is terrible. They're shouting 'Death to the Jews' and attacking synagogues. It's completely out of control", he said. » | Monday, July 21, 2014
