"The Prosecutor General's Office has requested to block access to (online TV channel) Dojd and (radio station) Echo of Moscow," Dojd announced on his Twitter account.
According to Dojd ("Rain", in Russian), the two media are accused of having relayed "calls to commit extremist and violent acts" and published "knowingly erroneous information concerning the activities of Russian military personnel".
Shortly after, AFP journalists in Russia noted that the sites of the two media outlets had become inaccessible.
"Echo of Moscow is no longer on the air," its editor, Alexei Venedictov, also declared on Telegram.
Dojd and Echo, along with the Novaya Gazeta newspaper, distinguished themselves by not sticking to the Kremlin rhetoric in their coverage of Moscow's invasion of Ukraine, unlike the overwhelming majority of Russian media.
The Russian authorities have banned the media from using information other than that provided by the Kremlin, the army and the various ministries, which present the invasion of Ukraine as a simple "special operation" confined to the east of this country.
Russia is regularly presented by NGOs as one of the most restrictive countries in the world in terms of freedom of the press.
The country thus ranks 150th out of 180 in the latest Reporters Without Borders press freedom index.
Several media, including the Dojd channel, have been designated by the authorities as "foreign agents", an infamous label which aims to discredit them in the eyes of advertisers and the public, and to complicate their work with crushing red tape.
Echo of Moscow, partly owned by gas giant Gazprom, has always strived to cultivate its independence and is one of the country's most respected media outlets.
