Russia has significantly escalated its campaign against the messaging platform Telegram by charging its founder, Pavel Durov, with aiding terrorist activities and issuing an international warrant for his arrest.

Russia's Federal Security Service (FSB) announced on Wednesday that the charges are part of an ongoing criminal investigation. The agency accused Telegram's management of failing to remove channels, group chats, and automated bots allegedly used to coordinate sabotage, terrorist attacks, cyberfraud, and other criminal activities inside Russia.

According to the FSB, Ukrainian intelligence services exploited the platform to organize acts of sabotage, terrorist attacks, and mass killings. Russian authorities claim that these activities, along with operations attributed to organizations designated by Moscow as terrorist and extremist groups, resulted in numerous civilian deaths, including women and children, as well as billions in property damage.

Shortly after news of the arrest warrant emerged, Telegram's official account on X posted an image of Durov making an obscene gesture toward the camera, a move widely interpreted as a response to the Russian government's actions.

Russia has steadily tightened restrictions on Telegram since August last year. In February, the country's communications regulator, Roskomnadzor, stated that the platform remained in violation of Russian law and that restrictions would continue until Telegram complied with legal requirements.

Russian courts have reportedly imposed more than 100 million rubles (approximately $1.26 million) in fines on Telegram since the beginning of the year, primarily for failing to remove content deemed illegal under Russian law.

Kremlin spokesperson Dmitry Peskov said earlier this week that Russian officials had discussed restoring Telegram's full operations in the country but claimed that the company's representatives had shown little willingness to cooperate.

Pavel Durov, a Russian-born technology entrepreneur now based in Dubai, co-founded Telegram with his brother, Nikolai Durov, in 2013. The encrypted messaging platform has grown into one of the world's largest communication services, with more than one billion users.

Before launching Telegram, Durov founded VKontakte (VK), Russia's largest social networking platform. He left Russia in 2014 after refusing government demands to provide access to user data.

A vocal advocate of digital privacy and freedom of expression, Durov has frequently clashed with governments seeking greater oversight of Telegram. While supporters view the platform as a defender of privacy and free speech, critics argue that its limited content moderation has enabled the spread of propaganda, disinformation, and criminal activities.

The latest charges mark one of the most serious legal actions Russia has taken against Durov and Telegram, further intensifying tensions between Moscow and one of the world's most influential messaging platforms.
