An early-morning fire in the rabbi’s residence at a synagogue in northern New Jersey yesterday was caused by several Molotov cocktails and other incendiary devices thrown through a second-floor window, Bergen County authorities said.

Prosecutor John Molinelli said the incident is being investigated as an attempted murder and bias-related arson. Molinelli said lit aerosol cans also were used in the attack.

The fire occurred at Congregation Beth El in Rutherford at about 4:30 a.m. It’s the latest in a series of incidents targeting synagogues in Bergen County.

Rabbi Nosson Schuman told CBS 880 Radio that he saw a flash of fire outside his bedroom window before his bedspread caught fire. The rabbi said he got his wife and five children out of the building safely, and said damage to the building was minimal.

Within the last three weeks, a fire was intentionally set at a synagogue in Paramus and anti-Semitic graffiti was discovered at synagogues in Hackensack and Maywood.

Law-enforcement officials and representatives from more than 80 synagogues and Jewish day schools had been scheduled to discuss the incidents today.

The synagogues in Maywood and Hackensack are about a mile apart. The other two are within about seven miles of each other in Bergen County, near the Meadowlands sports complex.
