Moskva was sunk with a Neptun missile.
This story appears to be bogus.
The originator of these supposed quotes from Yevgeny Fyodorov is Anton Geraschenko — on X.
It pictures Fyodorov in a video. It looks a little bit odd, but I am not an expert in AI produced imagery. But . . . the figure is in uniform. That is not in doubt.
I went looking for Yevgeny Fyodorov and images for him. He has not held any ministerial positions that are military related. Every photo I found of him was in a business suit. He served 3 years in the military in the 1980s. Never again a posting for such things.
The avalanche of cover for this story looks contrived. I don’t think the video is him.
