QUELLE BBC
By Dina NewmanBBC News
The appearance of far-right activists, both foreign and home-grown, among the Ukrainian volunteers fighting in east Ukraine is causing unease.
Mikael Skillt is a Swedish sniper, with seven years' experience in the Swedish Army and the Swedish National Guard. He is currently fighting with the Azov Battalion, a pro-Ukrainian volunteer armed group in eastern Ukraine. He is known to be dangerous to the rebels: reportedly there is a bounty of nearly $7,000 (£4,090; 5,150 euros) on his head.
In a telephone conversation from an undisclosed location, Mr Skillt told me more about his duties: "I have at least three purposes in the Azov Battalion: I am a commander of a small reconnaissance unit, I am also a sniper, and sometimes I work as a special coordinator for clearing houses and going into civilian areas."

As to his political views, Mr Skillt prefers to call himself a nationalist, but in fact his views are typical of a neo-Nazi.
"It's all about how you see it," he says. "I would be an idiot if I said I did not want to see survival of white people. After World War Two, the victors wrote their history. They decided that it's always a bad thing to say I am white and I am proud."

'One stray liberal'
Mr Skillt believes races should not mix. He says the Jews are not white and should not mix with white people. His next project is to go fight for Syrian President Bashar al-Assad because he believes Mr Assad is standing up to "international Zionism".
Not all of Mr Skillt's views are widely shared in the Azov Battalion, which is about 300-strong in total.

He says his comrades do not discuss politics much, though some of them may be "national socialists" and may wear swastikas. On the other hand, "there is even one liberal, though I don't know how he got there", he adds, with a smile in his voice.
