Roskomnadzor, Russia's communications regulator, ordered public access to the site to be blocked on Thursday to comply with a court ruling that found the social networking firm guilty of violating data storage laws.

Kremlin spokesman Dmitry Peskov told reporters on Thursday the Kremlin was not worried the case would stir fears about censorship in Russia.

"There are no such concerns," said Peskov.
