A packed commuter train has derailed near the northern Italian city of Milan, leaving at least three people dead and around 10 seriously injured.
Several people were rescued from the wreckage of the carriages that derailed next to the Pioltello Limito station in the morning rush hour.
A problem with a track point is being investigated as a possible cause, police say.
Witnesses said the train trembled for a few minutes before the accident.
The Trenord train, carrying some 100 people, was heading to Milan’s Porta Garibaldi station from Cremona when it derailed at about 07:00 local time (06:00 GMT).
Services in the area were halted for hours.
“A train can derail for only two reasons; either through a structural collapse of the track or a collapse of the train. This is the first thing that needs to be cleared up,” said Raffaele Cattaneo, president of the regional council.
