Russia has started restricting some Telegram and WhatsApp calls, accusing the foreign-owned platforms of failing to share information with law enforcement in fraud and terrorism cases, the digital development ministry said on Wednesday.

Both platforms had their run-ins with the Russian authorities in the past. The Kremlin tried to block Telegram between 2018-20 but failed. After Russia’s full-scale invasion of Ukraine in 2022, the government blocked major social media like Facebook and Instagram, and outlawed their parent company, Meta, that also owns WhatsApp, as extremist.

Russia restricts WhatsApp and Telegram, accusing misuse for sabotage and terrorism. Putin supports a state-run messaging platform. WhatsApp and Telegram defend their encryption.
