More than 10,000 people were evacuated from central Turin on Sunday as experts worked to defuse a World War Two bomb.
Residents of the Italian city were told to vacate a “red zone” in the historic district.
A further 50,000 living further away were told either to leave their homes in advance, or to remain inside during the operation.
The British bomb, dropped on the city during WW2, contained 65kg (140lbs) of dynamite, authorities said.
Turin Major Chiara Appendino said a detonator at the tail end of the device needed deactivating.
