Preliminary information indicated the driver lost control of the vehicle, and Russia’s state-run Interfax news agency said he was believed to have been drunk at the time, however Moscow’s traffic authority later disputed that. Interfax later said the taxi driver had fallen asleep at the wheel.

There were no immediate details on the severity of the pedestrians’ injuries.
