One person was killed and eight were injured in a stabbing spree in the Finnish city of Turku on Friday, a hospital director said, after police shot one suspect and warned several others could be at large.

"I can confirm that eight people are in our hospital. One person is dead. The rest are in stable condition," Turku University Hospital director Petri Virolainen told AFP.

Police shot one suspect in the legs and arrested him. Security forces wrote on Twitter that police were "looking for other possible perpetrators".
