Volunteers in the fight for Ukraine

In Ukraine, Russians are fighting on the side of the separatists, according to some voluntarily, according to others by order. But the separatists are not the only ones who have foreign citizens among the paramilitary combat troops. An article by Al Jazeera gives a small insight into this world, where, among others, Swedes, Brits, and French in the Azov Regiment are fighting against the separatists, or as they themselves say "against the Russians."
