Train crash in Paris suburb reportedly kills more than seven passengers

350 passengers were on board a train that derailed outside Paris.

A rush hour commuter train crash is a Paris suburb has resulted in at least seven deaths and an untold number of injuries, according to local reports emerging after the afternoon crash.

The crash occurred as a commuter train arrived at a stop in the southern suburb of Brétigny-sur-Orge, shortly after 5 p.m. local time. French rail operators have said it is unclear what caused the crash.

The Telegraph reports that a red alert was issued and that train officials have confirmed that more than 385 people were on board the passenger train when it crashed. France's interior minister has said that "at least seven" deaths have been reported, but that number is likely to go up as the scope of the accident becomes clear.

French train operator, SNCF, released a statement confirming that four train cars slipped off the track, one of which had tipped onto its side. The company expressed its sadness at the incident and promised to mobilize its resources to help affected travellers. It suggested other rail commuters in the area postpone their journey.

Reports from French news organizations suggest the number of casualties could be higher and suggest some people have been crushed or electrocuted at the crash site. Emergency crews are on the scene.
