It may be linked to Russia, maybe not.
One can rest assured the Ukrainians will ascribe it to Russian state actors.
And they may be telling the truth.
The problem is, only the NeoCons will believe them...as they have some truth issues of their own. And, like CNN, nobody believes them anymore even when they tell the whole truth.
Of course it’s linked to Russia. Russians are dirtbags, and crippling entities, governments is what they do.
Ukraine is the last wall protecting the west from Russia. Russia will do anything to knock it down.
