VATICAN CITY, Sept. 19 (UPI) -- The threat of a possible terrorist attack has prompted the doubling of security around the Vatican's St. Peter's Square.
Although no specific threats were reported, additional police were deployed at Pope Francis' outdoor general audience Wednesday. The Italian news agency ANSA quoted unidentified sources in reporting that a "maximum level of vigilance" and a "high level of alarm" has been a part of Vatican routine.
