Russia on Friday demanded that Alphabet Inc's (GOOGL.O) Google stop spreading what it labelled as threats against Russian citizens on its YouTube video-sharing platform, a move that could presage an outright block of the service on Russian territory.
Google representatives in Russia did not immediately respond to a request for comment by email. Google representatives outside Russia also did not immediately respond to requests for comment.
The regulator, Roskomnadzor, said adverts on the platform were calling for the communications systems of Russia and Belarus' railway networks to be suspended and that their dissemination was evidence of the U.S. tech giant's anti-Russian position.
"The actions of YouTube's administration are of a terrorist nature and threaten the life and health of Russian citizens," the regulator said.
"Roskomnadzor categorically opposes such advertising campaigns and demands that Google stop broadcasting anti-Russia videos as soon as possible."
