An explosion at a kosher grocery shop near Paris damaged the store and injured four people. Police have not linked Wednesday afternoon's attack to the release of caricatures hours earlier by a Paris weekly depicting the Muslim Prophet Muhammad, including one featuring a haredi Orthodox Jew and a religious Muslim.
One report said the blast was caused by a grenade while another said a package bomb was left at the store.
The store in the Paris suburb of Sarcelles reportedly was full of shoppers after the Rosh Hashanah holiday beginning their preparations for the pre-Yom Kippur meal, Moshe Cohen-Sabban, president of the Jewish communities of Val d'Oise, told the French online edition of the newspaper Metro.
Richard Prasquier, the president of CRIF, the umbrella group representing French Jewish communities, told the television channel i>TELE that two men dressed in black had tossed an explosive device into the shop without saying anything.
"I have no reason to doubt the anti-Semitic character of this action," Prasquier said.
According to Metro, the injured shopper sustained contusions in both arms. The newspaper quoted Marc Djeballi, a member of the Sarcelles Jewish community, as saying the device was "a grenade, not a firecracker."
Sarcelles, which is known as "Little Jerusalem," is home to a large Jewish community that emigrated from North Africa in the 1960s.
