“Roskomnadzor demanded that YouTube immediately remove the imposed restrictions from the Roscosmos Media channel, as well as restore all video materials with the participation of the head of the Roscosmos state corporation D.O.
Rogozin," the statement says.
A similar request was sent to the administration of the American corporation regarding the restriction of access to the personal account and the associated YouTube channel of Russian State Duma deputy Nina Ostanina.
Earlier, Roskosmos reported that YouTube hosting had removed a video featuring Rogozin.
