Russian authorities have charged Pavel Durov, cofounder of the messaging app Telegram. He is accused of aiding terrorism.

An international arrest warrant has been issued for Durov. The FSB, Russia's security agency, announced the charge.

The agency stated that Telegram failed to remove certain channels, chats, and bots. These were reportedly used by Ukrainian special services and terrorist groups.

The exact nature of Durov's alleged involvement is not fully detailed in the initial announcement.

Telegram is known for its encrypted messaging services, which are designed to protect user privacy.

This development marks a significant escalation in the relationship between Russia and the popular messaging platform.

The legal implications for Durov and Telegram remain unclear at this stage.

Further details are expected as the situation develops.
