Following restrictions on Facebook on the same day, Russia's media regulator Roskomnadzorhas blocked Twitter on Friday, according to Russian news agencies.
According to Interfax and RIA Novosti news agencies, access to Twitter was restricted on the basis of a request of the Prosecutor General from Feb. 24 – the day of Russia's invasion of Ukraine.
A journalist of the Agence France-Presse (AFP) confirmed that Twitter was no longer refreshing its feed in Russia.
Roskomnadzor did not issue a statement to explain the reasons behind the decision.
Earlier on Friday, the media watchdog said it was blocking Facebook in Russia over several cases of "discrimination" towards state media.
The move was part of an unprecedented government crackdown on independent media and activists since the start of the Russian invasion.
The country's key remaining liberal media outlets have been shut down in recent days and a new law introducing harsh jail terms for publishing "fake news" about the war in Ukraine has forced others to abstain from covering that topic.
