France’s Jewish community came under attack once again Wednesday when a device that some reports indicated was a grenade exploded inside of a kosher supermarket as patrons did their post-Rosh Hashanah shopping.

At least one person was injured in the attack in Sarcelles, and police quickly cordoned off the area around the Naouri market. While communal officials were quick to denounce this latest act of apparent anti-Semitism, locals in the Parisian suburb called it a miracle that there was no loss of life.

“I received several calls from people who thank G‑d decided at the last minute to alter their shopping plans,” said Rabbi Menachem Bitton, whose father, Rabbi Yaakov Biton, directs Chabad-Lubavitch of Sarcelles. “There were so many people who could have been there and weren’t. This is miraculous.”

Soon after the attack, the city’s mayor and the president of the local Jewish community visited the scene. Officials also beefed up security at area Jewish institutions.

Several news reports spoke of two men dressed in black as tossing the explosive device into the store.

“I have no reason to doubt the anti-Semitic character of this action,” Richard Prasquier, president of CRIF, the umbrella group representing French Jewish communities, told a French television channel.

Back in July, a witness to the April massacre of three Jewish children and their teacher outside the Otzar Hatorah high school in Toulouse was attacked by two men while riding a train. The month before, three Jewish men came under attack while walking to a synagogue near Lyon.
