Investigators suspect that a train derailment in northwest France which injured 44, one gravely, was the result of sabotage, a police source told AFP on Saturday.
A fragment of rail was found on the track, with the possibility of a malicious act being treated as the main line of inquiry as a result, the source said.
Carrying 186 passengers, the train was running between the Normandy cities of Rouen and Caen when it derailed around 7:45 pm (1745 GMT) Friday.
Authorities activated a mass-casualty response plan, with 130 firefighters, five medical teams and 80 vehicles drafted in.
