Italians Costantino Ragusa and Silvia Guerini, and Italian-Swiss Luca Bernasconi, were arrested and jailed after police conducting a routine traffic stop found a bomb in their vehicle. The three were stopped just a few miles from the IBM facility, which is due to open next year, on April 15. Police say a large quantity of explosives was found in the car. The AP reports that police also found a note indicating the planned attack on the facility.
The Daily Mail reports that all three were members of a terrorist group called Il Silvestre, while Gerini and Constantino – the 33-year-old leader of Il Silvestre - already have convictions for eco-terrorism offenses and have served time in prison.
According to DM, Swiss media reported that the intended bombing was planned to coincide with a secret meeting of European anarchists on April 16 and 17 in the Swiss town of Winterthur.
