Finnish police say two people have been killed and at least six others injured after being stabbed in a knife attack in the western city of Turku
It was not immediately clear if the attack near the city's central Puutori Square on August 18 was terror-related or fueled by a different motive.
The Finnish newspaper Helsingin Sanomat reported that eight people had been taken to the hospital following the stabbings, some of whom were in critical condition.
Police said that one suspected attacker was arrested on August 18 following a shoot-out, and that a manhunt was under way to find other potential "perpetrators."
"The government is closely following the events in Turku and the ongoing police operation. The government will meet later today," Finnish Prime Minister Juha Sipila wrote on Twitter.
Finnish police said security had been reinforced at Helsinki's airport and train stations after the stabbings.
"Police are looking for other possible perpetrators of the crime in Turku," Finnish security forces said on Twitter. "They ask the population to leave and avoid central Turku."
The deadly stabbing spree came a day after two suspected militant attacks in Spain killed 14 people.
