There is a ton of ups and downs with this story in general. Rumors have been flying around for about two weeks now, so I am also confused. Some pro-Ukranian telegram channels have been broadcasting news about this heavily, some haven’t. It’s just odd.
The media could be inflating rumors, which is possible. I think it’s also possible that this is part of a misinformation campaign to bait Russia into another poorly planned attack.
The only reason why I even speculate about this being misinformation is that Russia has been openly broadcasting about another attack on Kyiv. If that is the target or not, a change in leadership is a good time to attack something. This news would accelerate troop movements to somewhere and could be tracked easily.
This is just theory crafting, and it’s not a theory that I have read anywhere.
