"HTS fired shells and rockets at a Syrian military post, killing eight soldiers near Kafr Ruma in Idlib province," the Britain-based Syrian Observatory for Human Rights said.
It later reported that "three Syrian soldiers were killed by sniper fire" near Kafr Nabl in the same province, adding HTS jihadists were also responsible.
HTS is headed by ex-members of Syria's former Al-Qaeda franchise.
Syrian state media did not immediately report either attack.
About half of the northwestern province of Idlib and areas bordering the neighbouring provinces of Aleppo, Hama and Latakia are dominated by HTS and other rebel factions.
The Idlib region is home to about three million people, around half of them displaced.
Observatory head Rami Abdel Rahman told AFP that since the end of 2022, the jihadists "have intensified operations against regime forces in Idlib... in the context of a rapprochement between Ankara and Damascus".
He said exchanges of fire and clashes between regime forces and jihadist factions had killed more than 60 people since the start of the year, most of them pro-regime forces. One of the jihadists killed was a French national.
Ankara became a sworn enemy of Damascus when it began backing rebel efforts to topple the regime of Syrian President Bashar al-Assad at the start of the civil war.
- Re-branding -
But in late December the defence ministers of Turkey and Syria held landmark negotiations in Moscow -- the first such meeting since 2011.
The mooted reconciliation has alarmed Syrian opposition leaders and supporters who reside mostly in parts of the war-torn country under Ankara's indirect control.
Assad said in January that a Moscow-brokered rapprochement with Turkey should aim for "the end of occupation" by Ankara of parts of Syria.
Turkey has military bases in northern Syria and backs some local groups fighting the regime and against Syrian Kurdish forces which it considers "terrorist" groups.
Ankara has never publicly backed hardline group HTS but is believed to coordinate with its forces.
HTS, which is sanctioned by the UN as a terrorist organisation, formally broke ties with Al-Qaeda in 2016 and incorporated a number of smaller Syrian rebel factions in a major re-branding effort.
Widely seen as the strongest and best organised of Syria's rebel groups, it has presented itself as the mainstay of Syria's opposition.
With Russian and Iranian support, Damascus has clawed back much of the ground lost in the early stages of Syria's conflict, which erupted in 2011 when Assad's government brutally repressed pro-democracy protests.
The war has killed nearly half a million people since it broke out over a decade ago, displacing almost half of Syria's pre-war population.
Despite periodic clashes, a ceasefire reached in 2020 by Moscow and Turkey has largely held in the northwest.
