U.S. Not Alerted By Turkish Forces
Although a coordination center has been established in Ankara involving U.S., Iraqi, and Turkish military personnel to share information about intelligence and operations, U.S. military officials in Iraq were apparently unaware of an impending airstrike on PKK targets within Iraq until Turkish aircraft had already passed into Iraqi airspace.
Evidently, "hot pursuit" involving multiple strike sorties by Turkish forces didn't leave time for adequate (any?) notification.
Very unhelpful and intended as such, it might seem. This isn't an unreasonable assessment in light of recent events. I can only hope that Abdullah Gul has appeased Turkish pride, assuaged his political advisors and can now get down to the business of properly coordinating these missions for best military effect.
