Access to the BBC's Russian language services has been restricted in Russia.
Russia's state-owned news agency RIA says other news outlets have also had access to their services limited.
Russia's parliament has passed a law making it an offence to spread fake information about the armed forces.
The Kremlin says it objects to the conflict being called a war instead of a special military operation.
Record numbers of people have read the BBC's Russian language news website since the invasion, seeking up-to-date information on the conflict.
On Thursday, one of Russia's last independent news outlets, TV Rain, stopped broadcasting after coming under pressure for its coverage of the invasion.
The channel ended its final broadcast by showing staff walking off set.
