Well, I have spent some time looking for some articles describing how the Russian speaking Ukrainians were killed by Ukrainian  nationalists and here is 1 article that I found but it's in Russian: https://news.rambler.ru/conflicts/49388723-vosem-let-terrora-kak-vsu-i-natsbatalony-istreblyali-naselenie-donbassa/

At the same time I found at least several articles describing how allegedly the Russians killed Ukrainians but I am sure that all of these articles are a lie because since 2013 or even earlier the Western media of disinformation started a campaign of disinformation whereby they set a goal to prove to the whole world that it was Russians who were bad guys.

Provocation with MH-17 plane in 2014 was arranged and organised by the CIA with the same goal: to portray Russians as bad guys.

This is an example of a job done by the CIA. To me this is as clar as a day.   

It is preposterous and absurd to claim that the Russians have been killing Ukrainians. Only dumbed down people can believe in this BS.
