ANKARA, Oct. 9 (Xinhua) -- Turkish troops have crossed border into Syria's Idlib province as of Sunday to conduct reconnaissance mission there, the Turkish Armed Forces announced on Monday.
The operation in Syria's Idlib is under an international agreement to establish de-escalation zones agreed with Russia and Iran during the Astana peace talks.
"The military elements have started their expedition to establish observation sites during the operation," the Turkish Armed Forces said in a written statement issued on its website.
The reconnaissance mission is being conducted within the rules of engagement agreed between the guarantor countries, it added.
Turkey's latest military intervention followed Operation Euphrates Shield launched in August 2016, which backs the Free Syrian Army forces to clear Islamic State from Turkey's borders.
