Mr. Peskov, the Kremlin spokesperson, said Telegram had been questioned by the Russian authorities, but that its founder, Pavel Durov, had not been arrested in Russia. "In this country, nobody has arrested him. Of course, there were questions before," Mr. Peskov said in an interview. "Yes, terrorists do use the Telegram network, but terrorists also use cars. Why don't they arrest the general managers of Renault or Citroen?" Mr. Peskov said.
