Turkey issued diplomatic note to Syria about shooting down of the military jet, diplomatic officials said.
Earlier in the day Turkish Foreign Minister Ahmet Davutoglu said that Turkish military jet was shot down by Syria in international airspace.
Davutoglu said the jet was shot down in the international flight zone 13 miles outside of Syria's flight zone.
The plane was on a training mission to test Turkey's own national radar system, he said, adding that it was unarmed and had no mission related to Syria.
"We will, without any hesitation, decisively take the necessary steps regarding the downed Turkish plane by Syria," he added.
