At least five people have died after a high-speed train hit railway workers in Italy on Wednesday night.
The workers were replacing part of a track near the town of Turin, Italian news outlet Ansa reported.
The mayor of Brandizzo, Paolo Bodoni, told local media an investigation was under way.
In a statement, Italian railway network (RFI) expressed its "deep sorrow" for the incident.
RFI also sent its "deep condolences" to the families of those who died.
Mr Brandizzo described the incident as "chilling" and a "huge tragedy".
The train driver was treated by an ambulance at the scene for shock, but was physically unharmed. Two rail workers are understood to have escaped unharmed.
Turin is a town in northern Italy, almost 700 kilometres (434 miles) north of Rome.
