ROME, March 30 (JTA) — A crude firebomb was hurled at Rome’s main synagogue, causing minor damage to the entrance. The synagogue was empty at the time of the Saturday night attack, and no injuries were reported. Italian police detained a suspect, a 34-year-old Egyptian who apparently seemed drunk or mentally disturbed. Jewish community sources played down the incident, characterizing it as the work of a disturbed individual. The shul, the scene of an 1982 Arab terrorist attack that left a small child dead, is heavily guarded by paramilitary police 24 hours a day.
