French officials investigate if malicious act caused train derailment
Officials say a rail fragment was found on the tracks after Friday's crash of a passenger train that left 44 people injured.

Officials in northern France are investigating whether the derailment of a passenger train on Friday evening was the result of a malicious act.
"At this stage, the leading theory is that a piece of rail was present on one of the tracks, potentially causing the derailment. The reason for its presence is unknown," prosecutor Sébastien Gallois said on Saturday.
Local media say 186 passengers were on board the train that was operating between Rouen and Caen in Normandy.
"The main victim is still in hospital but her life is no longer in danger. The other victims have received care and treatment; they have either been discharged or are about to be."
