Reports: Suspected Bomb Discovered in Rome Metro

A device suspected of containing explosive powder was discovered in the subway system in Rome, Italian news reported today.

"Bomb disposal experts are looking into what it is -- whether it's a dangerous device that was capable of exploding or an inactive object," Rome's mayor Gianni Alemanno told Italian media. Later, Alemanno said bomb disposal experts told him the device "could not have exploded," according to a report by The Associated Press.

One news service said the potential explosives were left in a grocery bag underneath a seat and was spotted by a conductor, the AP reported. The stop, which is located on the outskirts of Rome, has been evacuated.

The discovery comes just a day after 12 men were arrested in the United Kingdom as they were allegedly in the final stages of a major bomb plot targeting several cities there.
