Russia's state communications regulator on Tuesday said it had blocked IP addresses owned by Google and Amazon, saying they were being used by the Telegram messaging service which Moscow moved to ban this week.

Russia's Roskomnadzor watchdog began blocking Telegram, a messaging service popular in Russia, on Monday after it refused to comply with a court order to grant state security services access to its users' encrypted messages.
