A day after Turkey shot down an unidentified drone near the country's Syrian border said it would not hesitate to shoot down planes violating its air space, Prime Minister Ahmet Davutoglu said on Saturday.
Syrian, Russian and U.S. coalition aircrafts are flying combat missions near Turkey's borders as part of the Syrian civil war.
"We downed a drone yesterday. If it was a plane we'd do the same. Our rules of engagement are known. Whoever violates our borders, we will give them the necessary answer," Davutoglu told a rally of his ruling AK Party.
Officials worry that Turkey, with the second largest army in NATO, could be drawn into military confrontation.
