Earlier this month, Iranian supreme leader Ayatollah Ali Khamenei said the country’s government entities would no longer be using messaging app Telegram, and now, Iran’s judiciary has banned its use altogether, as reported by Reuters.

The news comes on the heels of Russia’s own Telegram ban, enacted by blocking 15.8 million IP addresses on Amazon and Google’s cloud platforms and leading to large-scale “collateral damage.” As for how Iran will deal with its ban, the National Cyberspace Center withdrew Telegram’s license to operate in the country, and judiciary website Mizan quoted a court order saying, “All Internet providers in Iran must take steps to block Telegram’s website and app as of April 30.”
