You don’t need too much cognitive skills to find connections between Ukrainian ‘right-wing’ groups and Chechen insurgency.
It is not like all the Ukraine is guilty because of that, but it’s a fact.
Every "news item" that makes this connection ultimately links back to claims made in Russia Today, the propaganda arm of the Putin regime.
That is correct.
The Gruppenführer of Right Sector, Dymtri Yarosh, stated in an interview he gave late last year that his organization had sent fighters to Chechnya and that he himself had fought against Russians there.
Sashko Muzychko was another Right Sector trizub who bragged about killing Russians in Chechnya, and I'm sure there are others.
