The Islamic State's Aamaq news agency hours later claimed the attacker was "an Islamic State soldier".
'The version that the attack was a terrorist one is not the main one, ' the interior ministry added. Two of them being in serious condition, said the government of the region of Khanty-Mansi in a press release. An earlier statement said eight people had been wounded, but that was later revised to seven, BBC reported.
Surgut, with a population of about 320,000, is an oil- and gas-producing centre 2,100km (1,300 miles) north-east of Moscow. It said armed police called to the scene "liquidated" the attacker following the stabbing on Saturday morning.
The assault came within days of deadly attacks in Spain and Finland.
