Italy's state broadcaster is reporting that the FBI has passed on information to Italian authorities about possible targets for terror attacks, including St. Peter's in Rome and Milan's cathedral and La Scala opera house.

RAI state radio said early Thursday that "there are no direct signs of concrete threats" in connection with the information. It quoted unidentified Italian government officials as saying Italy receives information from many sources and is neither underestimating nor over-emphasizing the information.

Pope Francis' weekly audience was held on Wednesday without incident in St. Peter's Square,although his bodyguard contingent was reinforced. La Scala's season begins with a gala premiere on Dec. 7, Milan's patron saint's feast day. Some 700 soldiers are being deployed in Rome for security since last week's Paris attacks.
