That tidbit comes from NATO boss Anders Fogh Rasmussen, a man who sees all the top secret files and therefore knows what he's talking about.
This assertion is obviously intended to besmirch the anti-fracking movement in Europe by tarring them as Putin sympathizers.
It could however have the opposite effect...
"Say what? Putin is against fracking? Well, by jove, I knew he was against freedom and apple pie, but by golly... against fracking you say? Maybe he's not such a bad sort after all!"
