Who was it did the terror attack in Moscow?
Seymour Hersh is no mainstream stooge. He broke the Pentagon Papers mega story, and published "The U.S. was responsible for the Nordstream pipeline explosions”.
So, not a big fan of the U.S. military-industrial complex.
And he's got connections.
I don't know who carried out the Crocus terrorist attack in Moscow. And neither does CNN. And neither do you.
For the time being, until I see better evidence, I'll go with Seymour's info. It was ISIS.
