A large number of vehicles belonging to the Turkish military entered Syria from the Kafrlosin border crossing, APA reports citing Al-Arabiya.
According to the broadcaster, the convoy is heading in the direction of Aleppo and Idlib.
The news comes after earlier this week Turkish President Recep Tayyip Erdogan accused Damascus of violating a ceasefire in the region and warned that Ankara may launch a military offensive unless the operation there is "quickly halted".
