"Intelligence reports say that militants are leaving the areas under their control," he said.

"There is panic and desertion among their ranks," the general said. "Nearly 600 mercenaries have abandoned their positions and are making attempts to get out to Europe."

On Wednesday, Russia’s Federation Council empowered the president to use Russian military outside the national territory. The air operation was launched against Islamic State in Syria at the request of Syria’s President Bashar Assad. Earlier, Putin said that Russia would not be involved in operations on the ground.

Since Wednesday, Russian Air Force’s aircraft have been bombing Islamic State facilities located in Syria.
