OK. So far, googling one story on the twitter feed:
At Ukraine 24, the head of the military medical service talks about the fact that the order was given to castrate wounded Russian soldiers, because they are “cockroaches, not people”
No You Tube link. But this.
Ukrainian Medic Apologizes After Saying Russian POWs Should Be Castrated
Can’t cut and paste the article about sewing the Dnepopotrovsk dead Russian soldiers in pig skin.
Azovs in National Guard want to grease bullets with lard. Also un-cuttable.
All pretty dated, going back to March. Nothing about death squads so far. Any reports of castrated Russian POWs? IRC have anything?
