France is boosting security at Jewish religious sites after blank bullets were fired on a synagogue west of Paris.

French President Francois Hollande met Oct. 7 with leaders of the country’s Jewish community, and pledged to fight extremism and anti-Semitism “with the greatest firmness.” He said that authorities will increase security at Jewish religious sites so they won’t be subject to the kind of attack that targeted a synagogue in the Paris suburb of Argenteuil on Oct. 6.

A representative of the synagogue says the building was targeted with about eight blank bullets and services were canceled. The representative, who spoke on condition of anonymity because a police investigation is under way, said no one was hurt in the incident.

The attack on the synagogue came hours after police carried out raids across France against suspected Islamist cells. According to preliminary witness statements, the shots came from a car which slowed down as it approached the synagogue, before accelerating and fleeing the scene.

“A person… heard a bang and saw flashes. They fired blanks; there were no impact signs from the bullets,” a witness told police.

Board of Jewish Communities in Val-d’Oise Chairman Moshe Cohen-Sabban told Le Parisien: “This was an act that was more against the Jewish community. This is very worrying.”
