.....rumors that Israel is allowing the Russian airforce to fly over the Golan airspace ( which they control) to take out terrorists elements, and provide support to Russian pilots in case they get shot down. Interesting if true but not surprising.
al Nusra Front (Al Qaeda in Syria) based near Golan. Russia has been hunting down Al Qaeda and Muslim Brotherhood factions (to the criticism of the US which claims Russia is not targeting ISIL, which I guess means Obama considers Al Qaada/Nusra Front to be part of our moderate allies))
