WhatsApp said Russia was trying to block its services because the social media messaging app owned by Meta Platforms offered people's right to secure communication, and vowed to continue trying to make encrypted services available in Russia.
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.

"We will keep doing all we can to make end-to-end encrypted communication available to people everywhere, including in Russia."
