Mumbai, July 29 (IANS): Russia's Federal Security Service (FSB) on Wednesday charged Telegram founder Pavel Durov with facilitating terrorist activities, accusing the messaging platform of failing to remove content allegedly used to coordinate sabotage, terrorism and cyber-fraud operations within the country. The Russian security agency also said it had issued an international arrest warrant for Durov. There was no immediate response from either Durov or Telegram to the allegations. Telegram, the encrypted messaging platform launched by Durov in 2013, has grown into one of the world's largest messaging services, with more than one billion users globally. French authorities are separately investigating whether Telegram failed to adequately curb criminal activity on its platform and did not sufficiently cooperate with law enforcement requests.
