Two trams collided in a tunnel in a rare accident in the eastern French city of Strasbourg on Saturday, injuring dozens of people, the authorities said, reports Yahoo! News.
The collision occurred near Strasbourg's main train station, one of the busiest in France outside of Paris.
In 1994, Strasbourg was the first major French city to re-introduce trams, after the service closed in 1960.
Since the return of the vehicles, there have been no major accidents.
According to the prefecture, citing preliminary estimates, between 30 and 35 victims were injured. Firefighters put that figure at around 50.
A video posted by a witness on social media showed a chaotic scene with the two trams significantly damaged in a tunnel near the station.
