A fight involving several people broke out around 8 a.m. local time (0700 GMT) on a suburban train at Ozoir-la-Ferriere station, resulting in four injuries. Two of them were seriously wounded: one had a hand severed, while the other suffered a skull fracture, said the report.
According to France's national railway company SNCF, the train has come to a stop at the platform, leading to disruptions on the RER E line, with several trains canceled.
