Russia's main domestic security agency has charged Pavel Durov, the founder of the messaging app Telegram, with aiding terrorism and placed him on an international wanted list. The charges, announced Wednesday, stem from allegations that Telegram has hosted tools used to coordinate deadly attacks and sabotage across Russia. Durov, who was born and began his career in Russia but later moved abroad, now faces a criminal case as part of Moscow's broader effort to tighten control over the internet. Telegram remains one of the most popular messaging apps in Russia, and the charges come amid ongoing restrictions by Russian authorities. The move marks an escalation in pressure on the platform, which has been accused of enabling extremist activities. Details of the specific charges and the evidence behind them have not been disclosed. Durov's whereabouts are unclear, and it is unknown whether he will contest the allegations. The case underscores the increasing tension between the Russian government and technology platforms that it claims are used to undermine state security. Telegram has not yet issued a formal response to the charges.
