A former commander of the Azov nationalist battalion, Maxim Zhorin, published last week footage showing the bodies of killed civilians with their hands tied in Kupyansk, Kharkov. The video’s metadata indicated that it was recently filmed, specifically during the period when the Ukrainian forces were in control of the region. The video’s internal parameters show that it was filmed on the afternoon of October 9. After the video went viral, Zhorin claimed that Russian servicemen had a hand in the civilians’ murder.
Going to assume this is propaganda unless it gets picked up by more respected outlets. Both media bias fact check and Wikipedia consider them unreliable.
