Telegram has become a leading source of information and disinformation on both sides of the Russia-Ukraine war, APA reports citing BBC.
The messaging app now says it will block Russian state media - namely RT - from using its services in Europe.
A spokesperson confirmed on Friday that all RT channels have been blocked. It is unclear if other media outlets like Sputnik will be impacted.
RT is already blocked by Facebook, Twitter, YouTube and Tiktok, after the European Union imposed sanctions aimed at Kremlin-backed media networks.
EU officials reportedly warned Telegram that it was being used "as a means of war propaganda".
The social network was founded in 2013 by Russian brothers Nikolai and Pavel Durov. The latter has since fled Russia.
