No, the only fascists are the ones that crossed the border into Ukraine and are currently being pushed out. According to the article you linked, it states it's not possible to conclusively prove who launched those cluster munitions in October.

I've noticed the Russian Fascists haven't had a problem using cluster bomb on civilians, targeting hospitals and non-military health care facilities and generally committing random warcrimes.

You know, the simple solution for the war crimes to end would be for the Russian invaders to admit they fucked up, retreat to the borders that were recognized in 2013 and start preparing for the trials at The Hague.

But, Putin is too weak and much like Tankies need to tank... Russian fascists need to fash.
