Eight people have been injured by a knife attacker in Russia's far northern city of Surgut.

A knife-wielding man has wounded eight people in a Siberian city before being shot dead by police, Russian officials say.

The motive for the mid-day attack on a central street in Surgut on Saturday has not been determined, the regional branch of the Investigative Committee said.
