What insult? You cite one of the worst propagandists on the internet. Not an insult, a fact. Proven by his disproven insane conspiracies, not that you care of course. I mean you can forgive a journalist making a mistake, you really shouldnt forgive insanity.
That site is garbage. But they still reported a fact- which is now being reported by many other outlets. Mainstream news is behind on almost all aspects of this war. Russian citizens are becoming the best sources for news. Sifting through what's real or not is a challenge.
Did you know that there have been many acts of terrorism/sabotage within Russia? Very few have received media coverage. There are videos to back them up if you look hard enough.
