Finnish police said they were searching for additional perpetrators in the city and have urged people to be alert at train stations and near Helsinki-Vantaan airport, according to CNN.

The incident immediately raised concerns about international terrorism given a summer of attacks in European cities, some involving men with knives.

On Thursday, a van drove into a crowded pedestrian area in a historic district in Barcelona, Spain, popular with tourists, killing at least 14 people. Secretary of State Rex Tillerson on Friday said one of the dead was an American citizen. 

The Islamic State in Iraq and Syria claimed responsibility for the Barcelona attack. 

In Turku, a city 85 miles west of Helsinki, authorities are urging people to stay away from the area of the stabbings.
