A Ukrainian soldier named Serhiy, returning from Russian captivity, has reportedly been found mutilated with swastikas carved into his forehead, as disclosed by Dr. Olexandr Turkevich, who is treating him.
The soldier, blindfolded during the ordeal, claimed Russian soldiers threatened to dismember him, citing accusations of fascism.
Explained this in my answer; long story short, the very idea of such invasion was super unthinkable to an average Russian, and, while we’ve seen news from Western media, we discarded them as sensationalist and lacking understanding of the real situation.
But, as we soon figured out, Putin has no issue crossing any red line.
