In another part of Finland, the police arrested a man for throwing a Molotov cocktail at an emergency shelter for migrants. No injuries were reported and the fire was extinguished.

Finland’s three-party coalition government said in a statement on Friday that it “strongly condemns last night’s racist protests against asylum seekers.”

Despite ideological differences, Prime Minister Juha Sipila, Finance Minister Alexander Stubb and Foreign Minister Timo Soini, who lead Finland’s three largest parties, urged their supporters to accept that “Finland is an international, open and tolerant country where the majority accept migrants.”

Images of the faux Klansman, carrying Finland’s flag in one hand and a megaphone in the other, prompted a wave of outrage from Finns on the opposite side of the political spectrum.
