Turkish troops travelling in a convoy of 12 armoured vehicles have entered northern Syria in a new military operation.
Turkish news media reported that the vehicles carrying the troops crossed into Idlib province late on Thursday, Aljazeera reports.
The development came after Turkey said it was sending troops into Syria to enforce a de-escalation zone in Idlib.
The de-escalation zone forms part of an agreement reached between Turkey, which backs forces battling the government of President Bashar al-Assad, and Iran and Russia, which support his government.
Turkish media sources said the convoy included about 80 soldiers.
Local sources told Al Jazeera the troops were headed towards the western part of Aleppo province.
