Russia on Sunday put Meta Platforms spokesperson Andy Stone on a wanted list on unspecified charges as the US social media giant -- which owns Facebook -- is classed as "extremist" by Moscow.

Russia has cracked down on media and social media freedom since the war with Ukraine and banning criticism of the confict.

Stone is listed on Russia's interior ministry's list of wanted people, without further detail.

In October 2022, Russia listed Meta as a "terrorist and extremist" organisation, opening possible criminal investigations and fines for users in the country.

Facebook and Instagram have been blocked in Russia since the start of the Ukraine war and are only accessible via VPN.

Twitter is also banned, as well as Russian independent media critical of the Kremlin.

Before the bans, millions of Russians used applications belonging to Meta, especially Instagram, which remains hugely popular with young Russians.

In April 2022, Russia put Meta CEO Mark Zuckerberg on a blacklist of people banned from entering the country. (AFP)
