There were three bomb scares on Rome's metro lines Thursdayand one at Milan's Duomo station

All turned out to be false alarms amid fears that hysteria might be taking hold after terror alerts. Bomb alerts led to the closure of Rome's A line twice Thursday. The line was closed between Ottaviano and Battistini after a suspicious package was found in a carriage at Cornelia station. Earlier, the C line was closed between the stations of Torrenova and Grotte Celoni after two suspicious freezer bags were spotted, but it turned out to be a false alrm - like another case on line A earlier in the day.
