Six Turkish soldiers have been killed and nine wounded in shelling by Syrian government forces in Syria’s north-western Idlib province, Turkey said.
It said up to 35 Syrian troops had been killed in retaliatory fire. Syria’s media said there were no casualties.
Hundreds of thousands of people have fled an offensive by Syrian troops and their Russian backers against the last opposition stronghold in Idlib.
Many have moved towards the border with Turkey, which supports the opposition.
