Turkish Foreign Minister Mevlut Cavusoglu says a "comprehensive" fight against Islamic State (IS) militants will begin soon.
Cavusoglu said at the ASEAN summit in Kuala Lumpur on August 5 that U.S. drones and aircraft have begun arriving at Turkey's Incirlik air base near the border with Syria.
"Soon [the United States and Turkey] will together start an extensive battle against Daesh [IS]," Cavusoglu said, and that once an "comprehensive" fight started it would become safer for the nonextremist Syrian opposition forces to fight against IS militants.
Cavusoglu met with U.S. Secretary of State John Kerry in Malaysia on August 5.
Turkey carried out air strikes against IS targets in Syria in late July and agreed to allow U.S. fighter planes to use the Turkish air base for operations.
U.S. officials said the first armed drone missions out of Turkey began last weekend and that the military was planning to add manned aircraft flights soon.
