Adviser to the head of the Russian space agency Roscosmos Ivan Safronov suspected of working for one of NATO intelligence services is escorted at Lefortovo court, in Moscow, Russia. The investigators asked the court in to arrest Safronov. The Federal Security Service said earlier in the day that Safronov was suspected of handing classified defense information over to a NATO special service. Roscosmos said the detention was unrelated to Safronov's work for the space agency. A criminal case has been launched on suspicion of high treason.
