New Jersey law enforcement officials suspect that more than one person may be involved in what's being classified as a hate crime after a synagogue where nine people were living was firebombed.

Bergen County Prosecutor John Molinelli says several Molotov cocktails and other incendiary devices were thrown early Wednesday at a Rutherford home housing a synagogue on the first floor and the rabbi's residence on the second.

The rabbi, his wife, five children and the rabbi's parents were sleeping. Police say one device ignited in the rabbi's bedroom, and he suffered minor burns putting it out.

The prosecutor asks all northern New Jersey residents and religious institutions to be on alert. This is the fourth incident at a Jewish center or synagogue in recent weeks.
