At least seven people were wounded by a man with a knife who went on a stabbing rampage in the northern Russian city of Surgut.

No one was killed in the attack in the central Siberian city, but four of those hurt were in serious condition, according to state-run Tass news agency, who cited a regional health official.

Islamic State says the man — shot dead by police — was a "soldier" of the extremist group. However, Russian authorities say psychiatric information on the assailant is being sought, suggesting they believe the claim by ISIS may be opportunistic.
