Russia's Federal Security Service on Wednesday said it had charged Pavel Durov, the billionaire founder of the Telegram messaging app, with aiding terrorist activities.
The agency also issued an international warrant for his arrest.
The FSB said the charge formed part of "an ongoing criminal investigation" against Durov.
Why is Russia charging Durov?
The security service accused Telegram's management of failing to remove channels, chats and bots allegedly used to organize attacks and acts of sabotage inside Russia.
