Isis has claimed responsibility for a stabbing attack in Russia that injured eight people, the group’s Amaq news agency has said.
An attacker was killed by police after knifing people in the Siberian city Surgut on Saturday morning.
Russian authorities had earlier declined to comment on whether the incident was being treated as a terrorist attack.
The state-owned RIA Novosti agency said two people were in critical condition in hospital.
It happened at about 11.20am local time, Russia Today reported.
Surgut, with a population of about 320,000, is an oil- and gas-producing centre 2,100km (1,300 miles) northeast of Moscow.
