Turkish drone strikes on Idlib have killed nineteen Syrian soldiers, a UK-based monitor has said.
The Syrian Observatory for Human Rights (SOHR), based in Coventry, said the attacks targeted a military convoy and an army base.
The fighting has sparked one of the war's worst humanitarian crisis, with almost one million Syrian civilians fleeing towards the sealed Turkish border.
The Turkish military launched operation "Spring Shield" to defeat Syrian government forces and to prevent a massive wave of immigration.
Turkey supports fighters in Syria's Idlib province, where the last remaining rebel forces in the country are holed up, and has sent thousands of troops into the area.
Tensions escalated after Turkey lost 54 soldiers in February, including 33 killed on Thursday in a single airstrike.
Since that airstrike, SOHR said Turkish drone strikes have killed 93 Syrian government forces and allied fighters.
Outraged following last week's events, Turkey's President Recep Tayyip Erdogan announced his country's European borders were open on Saturday for thousands of migrants and refugees as he sought to pressure Europe to help Turkey handle the fallout from the war in Syria.
The new gains at Saraqeb on the ground also bring the last segment of a highway that links the capital Damascus and the major northern city of Aleppo under government control. The highway was reopened late last month before insurgents seized Saraqeb, which sits on the highway, last week.
On Sunday, Turkish troops shot down two Syrian warplanes after the Syrian military downed a Turkish drone, a major escalation in the direct conflict between Syrian and Turkish forces.
The government-controlled Syrian Central Military Media said Syrian troops and their allies regained control of Saraqeb after fighting with al-Qaida-linked militants.
The Britain-based Syrian Observatory for Human Rights said troops captured the town under the cover of airstrikes by the Russian air force.
Syrian government forces have captured dozens of villages since they launched a Russian-backed offensive in Idlib in early December leaving hundreds of civilians dead and displacing more than 950,000 triggering a humanitarian crisis.
