The report documents horrendous torture and it was done out of racial hatred of Russians. You can read the report here:  https://www.osce.org/files/f/documents/e/7/233896.pdf 

 Few Westerners, being so poorly educated, are aware that Western Ukraine fought for Nazi Germany during World War II.  When Washington overthrew the Ukrainian government in 2014, Washington installed a Nazi government. The Nazi government in Ukraine shelled the Russian residents of the two break-away Donbass republics for 8 years while Washington and NATO trained and equipped a Ukrainian army to retake the breakaway republics. 

The Donbass region, always a part of Russia, was put into the Ukrainian province of the Soviet Union by the Soviet government for administrative or other reasons, as was Crimea by Khrushchev in the 1950s.  When the US overthrew the Ukrainian government and installed an anti-Russian government, the residents of Crimea and Donbass, being Russians, broke away and voted overwhelmingly to be reunited with Russia.  The Kremlin accepted Crimea but made the strategic blunder of rejecting Donbass, thus resulting in the extreme murder and torture of Donbass Russians for 8 years before the Kremlin was forced to intervene by Russian public opinion and by the appearance of a 150,000 American-trained Ukrainian army and Nazi militias on the Donbass border.
