Iraqi government sources report firing on Royal Saudi Air Force jets.  The Saudi planes were engaged north and east of Baghdad and quickly withdrew to Saudi air space.  Sources indicate there is no question, the Saudi planes were attacking Shiite militias and providing close air support for ISIS.

Recent intelligence reports have confirmed Saudi Arabia as the source for air resupply drops previously blamed on the US.  Reports now indicate that the Royal Saudi Air Force has forward air controllers operating with ISIS forces.  Saudi forces have been captured inside Syria while operating there with al Nusra.

After today's Saudi attack on Iraq, any coalition planes flying in Iraqi air space may well face attack by Iraqi air defenses.
