A Turkish official says a plane has crashed in the countryside near the Syrian border with preliminary information suggesting the aircraft belonged to Syria.
Hatay province governor Erdal Ata told state-run Anadolu news agency that it was "likely" a military aircraft, but that there was no airspace violation and no intervention by Turkish forces, adding that it might have been a technical problem.
Rescue teams have been dispatched to the area.
Private Dogan news agency reported nearby villagers had called authorities reporting a crash at around 6:30 pm local time (1530 GMT) on Saturday.
They also told authorities that the pilots had allegedly ejected before the crash.
