The BBC website, Facebook and Twitter were blocked yesterday in Russia.
State censorship agency Roskomnadzor cut off access during a Kremlin crackdown.
BBC boss Tim Davie said: “Truth is often the first casualty of war.
“In a conflict where disinformation and propaganda are rampant, there is a need for factual, independent information that people can trust.”
The Russian Foreign Ministry said the BBC was “undermining domestic political stability and security”.
Along with Facebook, the regulator said there have been 26 cases of discrimination against Russian media by the platform since October 2020.
Radio Free Europe, one of the largest independent news outlets on the continent, and Maduza, one of Russia’s largest exile news sites, were also banned.
RFE personnel were called “foreign agents” and expelled from Moscow HQ.
Russian media have been warned not to call the situation in Ukraine a “war”, but to call it a “special operation”.
