A bottle of flammable liquid was hurled at one of Chicago's oldest synagogues, catching fire but not causing major damage. No one was injured in the incident early Monday at Temple Sholom of Chicago. Chicago police and the Chicago fire department are investigating the arson as a hate crime. No one was in custody Monday. Police officer Daniel O'Brien says the fire burned itself out and never ignited the North Side building. He says investigators are working to get surveillance equipment from the area. Roger Rudich, president of the temple, says the arson was unsettling but not damaging.
