A bomb alert at the Colosseum in Rome was canceled after a suspicious device was found to be harmless, officials say. The Carabinieri bomb squad officials said they believed a barrel found Sunday under some arches in the monument was a fake and could not be exploded, Agenzia Gionalistica Italia reported. The bomb squad had intended on neutralizing the suspect drum, which was half filled with turpentine with two electrical wires running out to a 9-volt battery.
