The bomb squad of the 6th pioneer engineering regiment of the Army defused an airplane bomb weighing approximately 2.000 kg, dating back to the Second World War, found in the center of the Municipality of Viterbo.
The operations, coordinated by the prefecture of Viterbo, began at six o'clock with the clearing of an area of ​​1.400 meters in radius from the point of discovery of the residue and the consequent evacuation of approximately 36.000 citizens. For the safety of the area, a ban on overflight of the affected airspace has been established, as well as the closure of rail traffic on the Rome - Viterbo regional railway line.

The operators of the 6th Pioneer Engineer Regiment, once the evacuation phase was completed, began the defusing operation at 10am to remove the three fuses, the bomb activation devices, all activated and armed. Once these were neutralized, the war residue was transported to the 25th "Roma" regiment, where it was rendered harmless with the leaching technique, which involves emptying the bomb using jets of high-temperature water, capable of dissolving the explosive and convey it into a filtering system, in order to separate the compound, for subsequent destruction of the explosive.

In 2023, the bomb disposal teams of the engineering regiments conducted 2.356 interventions throughout the national territory, neutralizing 12.666 war remnants of which 21 aircraft bombs dating back to world conflicts.
The bomb, with a diameter of 76 cm, 2.08 m long and 0.77 cm thick, contains over 1.300 kg of explosives inside. The 2.000 kg bomb is of the largest type and is the sixth found in Italy.

To limit the evacuation area and the resulting inconvenience to the local population, the military created a containment structure capable of mitigating the possible effects due to a possible accidental explosion during the delicate defusing activities. This allowed the clearing radius to be reduced to just 1.400 m. The distances are the result of recent studies and experiments carried out by Counter-Improvised Explosive Devices center of excellence of Rome.​
