Russian fighter jets have taken to the skies over the Crimean Peninsula during snap military exercises, Armed Forces 4th Army Vice Commander Col. Andrei Novoseletsky said Thursday.

"Radio technical troops conducted constant radar surveillance at a distance of over 400 kilometers. The coordinates of the air targets were forwarded to the aviation crews in the air using automated control systems," Col. Novoseletsky told General Staff Army Gen. Valery Gerasimov.
