HELSINKI, Aug 23 (Reuters) - Finnish police said on Wednesday they had arrested two more suspects in connection with last week's knife attack that killed two and wounded eight in the city of Turku.

The arrested men had told Finnish authorities they were from Algeria and Swedish ones they were Moroccan, police said.

Police have previously detained the main suspect, a Moroccan asylum seeker and three other men in connection with the killings, which they suspected of having had a terrorist motive.
