According to eyewitnesses cited in another report in Repubblica, the attacker shouted "Allah Akbar" - which translates as "God is great" - before stabbing people in the main square in the port city of Turku.

An arrest warrant has also been issued for another Moroccan man internationally.
A private person had informed local police of the attacker and the police had sent the information to SUPO, Yle said.
