Days after similar attacks against Jewish targets, shots were fired at a Paris publishing house owned by Jews on Thursday night.
Bullets holes were discovered at the entrance to the building on Friday morning, Israel Radio reported.
Investigators believe the shooter used a high-powered air gun, the same type of weapon used in the two previous attacks this week.
On Wednesday, bullet holes were discovered in the window of the Al Haeche kosher restaurant located in the 19th district of northeastern Paris. The attack occurred Tuesday night, the JSSNews website reported.
That bullet, too, was reportedly fired from an air gun. An air gun is believed to have been used Monday night when a bullet crashed through a window of the David Ben Ichay Synagogue in Belleville, in the northeastern section of the French capital. The synagogue is located less than a mile from the restaurant.
