Department of Defense spokesman Peter Cook also said yesterday that Washington has "no indication" the Turkish government had tipped off an Al-Qaeda affiliate group to help them go after US-trained Syrian rebels, as alleged in one report citing rebel figures.
The agreement with Turkey will incorporate Turkish planes into the "air tasking order" - or ATO - to ensure Turkish operations do not interfere with the operations of the coalition of countries targeting the IS group.
"It could take a few days [to put] these technical arrangements into place at the operational level. We believe that Turkey is committed to fully participating as soon as possible.
