A knife attacker stabbed eight people on the street in Russia's far northern city of Surgut before being shot by police, investigators said Saturday.
The male attacker carried out attacks on passers-by, causing stab wounds to eight while moving along central streets of the city at around 11.20am local time said Russia's Investigative Committee, which probes major crimes.
It said that armed police then arrived and used their weapons on the attacker and liquidated him.
The incident took place in a city some 2,100 kilometres northeast of Moscow in the oil-rich Khanty-Mansi region.
Two of those stabbed are in a serious condition while five more are in a stable condition, the government of the Khanty-Mansi region said in a statement, calling the attacker so far unidentified.
It called for calm over the incident, saying that in the interests of public calm and also of the investigation, citizens and media are recommended to use reliable information in assessing the situation until all the circumstances are established.
