Russia suspects Turkey plotting invasion of Syria
"We will return our historic debt. At one time, our brothers from Aleppo defended our cities of Sanliurfa, Gaziantep, Kahramanmaras, now we will defend the heroic Aleppo. All of Turkey stands behind its defenders," Davutoglu said.
Davutoglu made the statement after the Syrian military cut off terrorists' major supplies channels in northern Aleppo province from from Turkey.
Russian officials also expressed concerns about Turkey's possible attack on Syria. "We have serious reasons to believe that Turkey has been taking efforts to prepare a military invasion of the territory of a sovereign state - the Syrian Arab Republic. We have seen many signs of the hidden preparations of the Turkish armed forces for military actions in Syria," an official spokesman for the Russian Defense Ministry, Major-General Igor Konashenkov said.
Russian Foreign Minister also spoke about the possibility of a large-scale war in the region with the participation of neighboring countries.
"If the Geneva talks do not bring any results, they will opt for a military solution. The leaders of several countries have already made such point blank statements. As I can understand, they share almost personal hatred to Bashar Assad. I do not think that the coalition led by the United States, in which Turkey is included, will let such reckless plans materialize," said Sergey Lavrov.

Or it could be that Russia can't do anything about it anyways. It they want to give blessings, Putin would do it especially if he wants to get some influence and friendship with the Turkish leader right out in the public on this situation. Not criticize it.
