From an AP story by Erika Kinetz headlined “Antiwar officer from Putin’s elite security team defects”:

On October 14th, a Russian engineer named Gleb Karakulov boarded a flight from Kazakhstan to Turkey with his wife and daughter. He switched off his phone to shut out the crescendo of urgent, enraged messages, said goodbye to his life in Russia and tried to calm his fast-beating heart.

But this was no ordinary Russian defector. Karakulov was an officer in President Vladimir Putin’s secretive elite personal security service — one of the few Russians to flee and go public who have rank, as well as knowledge of intimate details of Putin’s life and potentially classified information.
