Turkish President Tayyip Erdogan said developments were turning in Ankara's favor, three weeks after the armed rebel opposition lost the northwestern town at the crossroads of two main highways to the Russian-backed Syrian government forces.
The Syrian army has pushed hard in recent months to retake the last large rebel-held region in northwestern Syria after nine years of war that has displaced millions and killed hundreds of thousands.
Turkey has sent thousands of troops and heavy military hardware into Syria's Idlib province in an incursion to back the rebels against the offensive by Syrian President Bashar al-Assad's forces.
