"Until the regime’s [Syrian government] forces pull out beyond the borders [of the Idlib de-escalation zone] outlined in the Sochi agreement, the problem will not be solved. If they do not leave, we will do this work without waiting until the end of February," Erdogan said in a speech in Istanbul, broadcast by the NTV channel.
Erdogan has repeatedly threatened military action unless Syrian armed forces halt their operation in Idlib and withdrew from the de-escalation zone by the end of the month.
The situation in Idlib has been tense for months. Tensions spiked recently after Turkish military units came under fire from Syrian government forces, and two Syrian helicopters were shot down.
Ankara has accused the Syrian government forces of violating the ceasefire in Idlib and has threatened military force unless the situation changes. Damascus, in turn, has defended its right to retaliate against continued militant attacks on civilians and government forces in Idlib.
