Turkey said two of its soldiers were killed Wednesday in a Syrian regime attack in northwestern Syria.
The Turkish Defense Ministry said in a statement said that the latest Syrian attack on its troops also wounded six soldiers, without providing further details.
Clashes between Turkish and Syrian regime forces in northwestern Syria have killed more than 50 Turkish troops in the past month, including 33 soldiers killed recently in a single airstrike.
Turkey has sent thousands of troops into the area but hasn't been able to stop the Russian-backed Syrian government offensive to retake the Idlib province, the Associated Press reported.
Moscow blames Ankara for the collapse of a ceasefire agreement reached in Sochi in 2018, saying Turkey has failed to honor the deal and rein in militants who continued attacking Syrian and Russian targets.
On Wednesday Russia's Ministry of Defence said that fortified rebel positions in Syria's Idlib province had merged with Turkish observation posts.
According to Reuters, the allegations by Major-General Igor Konashenkov, are likely to increase tensions ahead of a planned meeting on Syria between Russian President Vladimir Putin and his Turkish counterpart Tayyip Erdogan.
Turkey had poured enough troops into Idlib to make up a mechanised division, said Konashenkov, violating international law.
There was no immediate response from Turkey, which has traded blame with Moscow over the upsurge in violence in Idlib.
Erdogan is scheduled to hold a summit with Putin on Thursday in an attempt to make a ceasefire deal in Syria.
