Turkey may launch a military operation into Syria's northwestern Idlib province if the situation is not resolved immediately, President Recep Tayyip Erdoğan said Friday as attacks by Russia-backed regime forces risked a new wave of refugees.
Bashar al-Assad's forces, backed by Russian air power, have since last week rapidly advanced on Idlib. They have taken dozens of towns, including the key city of Maarat al-Numan, upending the last major rebel-held stronghold in Syria's nearly nine-year war.
The recent campaign has also raised tensions between Ankara and Moscow, which back opposing sides in the conflict. Turkey fears a fresh wave of migrants from Idlib and has 12 observation posts in the region, part of a 2018 de-escalation deal that Erdoğan says Russia is now violating.
Speaking in Ankara, Erdoğan repeated Turkey could not handle a fresh influx of migrants. He said Ankara will not allow new threats near its borders, even if it meant resorting to military power, as it did in its three previous cross-border operations in northern Syria.
"We will do what is necessary when someone is threatening our soil. We will have no choice but to resort to the same path again if the situation in Idlib is not returned to normal quickly," Erdoğan said.
He also appeared to hold out the option of another operation in northeastern Syria, where in October Ankara targeted the YPG which has been viewed by Ankara as Syrian branch of the bloody minded PKK terror group.
"We will not refrain from doing what is necessary, including using military force," he said, adding Turkey wants stability and security in Syria.
Later on Friday, the Kremlin said Russia was fully compliant with its obligations in Idlib, but that it was deeply concerned about what it said were aggressive militant attacks on the regime forces and Russia's Hmeimim air base.
Turkey, which has backed some rebels fighting to oust Assad, currently hosts more than 3.6 million Syrian refugees. Erdoğan has repeatedly called for Assad to step down, even while Iran, Russia and Turkey have said they seek a political solution to the conflict.
"We will not allow the regime to put our country under the constant threat of migrants by tormenting, attacking, spilling the blood of... its people," Erdoğan said.
