Turkey has been fiercely opposed to Syrian President Bashar al-Assad during his country's six-year-old civil war but has recently been working with his allies Russian Federation and Iran for a political resolution to the conflict.
The escalation of the fighting between Syrian government troops openly aided and abetted by Russian Federation and Iran on one hand and opposition militias deployed in the Idlib province - the only major swath of territory still in the hands of the opposition - is sparking a Turkish outcry for fear that the onslaught on opposition risks destroying the very foundation of the "de- escalation zone" arrangement in the province.
"Iran and Russian Federation should fulfil their responsibility. If you are guarantors, which you are, stop the regime", Cavusoglu said.
"This is not a simple air offensive".
Turkey protested the Syrian regime's advance into the rebel- stronghold on the grounds that regime troops are targeting moderate opposition in Idlib, arguing that the move undermined prospects of an upcoming meeting in Black Sea resort Sochi on January 29-30, where the regime and opposition groups will seek peaceful solution to the Syrian conflict. "They have a different intention". "If you are guarantors, which you are, stop the regime".
Hayat Tahrir al-Sham group, spearheaded by the former al-Qaeda affiliate in Syria that was known as the al-Nusra Front, is mainly dominating in Idlib.
Damascus has been scoring military successes against the rebel groups in the area thanks to Russian air support and active involvement of Iran-backed militias.
Turkey appeals to Russian and Iranian diplomats to urge Syria's government to cease violation of de-escalation zone borders' violation in Idlib, according to the newspaper. This is also the reason for Vladimir Putin's telephone conversation with Recep Tayyip Erdogan. "We have exerted so many efforts and we can not waste them".
A previous attempt in November to convene talks in Sochi failed due to disagreements between the prospective participants.
