Speaking in Antalya late yesterday, Foreign Minister Mevlut Cavusoglu says that operation could "easily advance to Raqqa," the main IS bastion in Syria.
American Special Operations forces and a coalition known as the Syria Democratic Forces have begun clearing areas north of Raqqa in preparation for an eventual assault on the city.
A major player in the coalition is the Kurdish People's Protection Units, or YPG, which Turkey unlike the United States views as a terrorist organisation.
Turkey is part of the US-led coalition against IS and a Turkish air base is being used to launch bombing runs against IS.
