The attack took place late Saturday in the northern suburb of Goussainville, police said. It comes a week after assailants tossed gasoline bombs at a Jewish school in the southeastern Paris suburb of Creteil, setting a classroom on fire.
Sammy Ghozlan, vice president of the Jewish consistory for the Paris region, expressed his "deep emotion" at the attacks on Jewish sites in France. "There is a great deal of worry in the community," he said.
A wave of anti-Semitic violence broke out in France in late 2000 after fighting between Israelis and Palestinians escalated in the Middle East. In most cases, incendiary devices were lobbed at synagogues.
