A Syrian government plane was downed in the northwestern Idlib province, Turkey's state-owned Anadolu Agency said on Sunday.
Turkish forces have been hitting Syrian government targets in Idlib in recent weeks. In February, a total of 55 Turkish soldiers were killed in Syrian government attacks, including airstrikes, in Idlib.
The government forces' airstrikes are part of a major assault to capture the province, part of the last remaining territory held by rebels backed by Turkey.
