A Russian court on Friday ordered the blocking of a popular messaging app, Telegram, after it rejected to share its encryption data with authorities.

The Moscow court on Friday ruled in favor of the Russian communications watchdog, which had demanded that Telegram be blocked in Russia until it hands over the keys to its encryption.

The ban comes after a protracted dispute between Telegram and Russian authorities, who insist they need access to the encryption keys to investigate serious crimes, including terrorist attacks. Telegram is arguably the first widely popular means of communications in Russia that has been officially banned.


Telegram, a popular app developed by Russian entrepreneur Pavel Durov, argues that Russia's FSB intelligence service is violating consumer rights, while authorities say the app has been used by violent extremists.

Durov had asked his lawyers not to attend Friday's court hearing because he said he saw the verdict as a foregone conclusion.

Pavel Chikov, one of Telegram's lawyers, said in a post on his Telegram channel that the company would not back down in the face of the Russian intelligence services because the court hearing, which lasted about 20 minutes, showed that the case against Telegram is politically motivated.
