A Russian military plane with 92 people on board has crashed into the Black Sea on its way to Syria. The plane, including members of a famed military choir bound for Syria to entertain Russian forces there, crashed into the Black Sea on Sunday after takeoff from the resort town of Sochi, the Russian authorities said. The plane disappeared from radar 20 minutes after taking off from the resort of Sochi at 05:20. The Interfax news agency cited an unnamed source as saying the plane had not sent an SOS signal.
