One person died and dozens, including five children, were injured when two trams collided in Russia's Siberian city of Kemerevo, the regional health ministry said on Thursday.
Footage on social media platform X appeared to show that the brakes had failed on one of the trams which caused it to take a bend at high speed before it hit the other tram further along the line.
Two people were thrown from the speeding tram across a road into the path of oncoming traffic.
"Ninety people were hurt, including five children," Alexei Kuznetsov, a senior official at the regional health minister, was quoted as saying by the Interfax news agency. "Unfortunately one person died."
