As many as 14 people were poisoned at a synagogue outside Paris Monday, in what investigators called an anti-Semitic attack.

The victims suffered from rashes and irritated eyes but were expected to survive. The attacker had applied a poisonous substance to the keypad of the synagogue's electronic lock, Le Parisien reported.

The church is located in Bonneuil-sur-Marne, roughly 10 miles southeast of the French capital.

Investigators did not say whether they've named a suspect. Police were still investigating, according to Le Parisien.

The new attack came one month after the Paris massacre that left 130 people dead, and less than a year after attacks on a kosher supermarket and the offices of the satirical newspaper Charlie Hebdo.
