ROME (AFP) - A parcel bomb was sent to the offices of Italian newspaper La Stampa on Tuesday but failed to detonate when opened, prompting an evacuation of the building as bomb disposal teams were deployed, the police and the daily said. “Inside there was a mechanical system, which did not function, but was capable of detonating a device,” La Stampa said on its website, which showed a photograph of the bomb in a type of hard case usually used for carrying CDs. The package was delivered to the newspaper’s headquarters in Turin in northern Italy and was opened by an employee of its publishing arm. The package had passed a metal detector without setting off alarms.
