A passenger train with several hundred people on board "has derailed in the southern Paris suburb of Brétigny, with authorities reporting 'many casualties,'" France 24 reports. Officials are still sorting through what French media are calling their country's worst rail accident in 25 years.
The BBC said initially that "at least eight people are reported dead. ... The intercity train had just left Paris and was heading towards Limoges when it derailed, crashing into a station platform. ... Passengers were said to be trapped inside the train."
Reuters reported that "7 people died and several dozen were injured. ... Interior Minister Manuel Valls said on Friday. 'The death toll is evolving constantly at this point and unfortunately it will probably rise,' Valls said. 'At this stage there are seven people dead, several dozen wounded and some of them are serious.' "
Le Parisien said in its first report that there were at least four dead and at least 10 injured.
