"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 in the central city of Kayseri, Reuters reported.
Turkey is still investigating where the drone came from.
A U.S. official said on Friday Washington believed it was of Russian origin, but the Russian defense ministry said all of its planes in Syria had safely returned to base and that all its drones were operating "as planned".
The Turkish military said it shot down the unmanned aircraft after it continued on its course despite three warnings, in line with its rules of engagement. Broadcaster NTV said it had come 3 km (2 miles) into Turkish air space.
As UNIAN reported earlier, Russia's Defense Ministry says it has established direct contact with Turkey's military to ensure flight safety of Russian combat aircraft near the Turkish border with Syria and prevent any future incidents, according to Radio Liberty.
Syrian, Russian and U.S. coalition aircraft are flying combat missions near Turkey's borders as part of the Syrian civil war. The drone incident highlights the danger that Turkey, with the second largest army in NATO, could be drawn into a military confrontation.
Turkey had already complained of Russian warplanes violating its air apace along the border with Syria earlier this month.
