OSLO, Jan. 18 (Xinhua) -- Norway's police intelligence service PST said Friday a stabbing of a woman in downtown Oslo by a Russian man was being investigated as a terrorist attack.
The stabbing occurred on Thursday afternoon inside a grocery store in Oslo. The woman is critically injured and is in hospital, local media reported.
The suspect was a 20-year-old Russian man who came to Norway from Russia via Sweden on Thursday, PST chief Benedicte Bjornland told reporters.
"He said that he wanted to kill several people and that it was a terrorist act," Bjornland said.
The PST chief also said it was too early to link the man to any concrete terrorist organization and there should not have been others involved in the knife attack.
The Russian Embassy in Norway said it knew the identity of the detained Russian citizen and was looking into the situation, according to Russia's Sputnik news agency.
"We are looking into the situation, and the embassy knows who the detainee is," Timur Cherkanov, press attache of the Russian diplomatic mission, told Sputnik.
"The embassy is in contact with (Norwegian) law enforcement agencies and clarifying details of the case," he said.
