Firefighters say two trams have collided in Strasbourg in eastern France, injuring dozens of people, though none critically.

Two trams collided at Strasbourg's central station on Saturday, injuring 68 people, authorities said. Reports said that one tram, which had been stopped, moved backwards down a slope for unknown reasons, colliding with another tram that was stationary.

Around 68 people were injured after two trams in the French city of Strasbourg accidentally collided inside of the city's central railway station on Jan. 11. Video footage of the aftermath shows screaming passengers attempting to get out of the tram cars as broken doors and windows litter the station.
