IDLIB (Dispatches) – One Turkish soldier has been killed and four have been wounded in the northwestern Syrian region of Idlib in a rocket attack on a supply convoy, Turkey’s Defense Ministry said.
"One of our soldiers was martyred and four were injured in the rocket attack on our supply convoy on May 10, 2021,” the ministry said in a statement, adding that the Turkish military opened fire in retaliation.
It did not say who carried out the attack.
The Turkish army launched offensives in 2016, 2018, and 2019 in northern Syria.
On March 1, Turkey waged its fourth cross-border incursion into Syria, days after an airstrike by Syrian forces killed dozens of Turkish soldiers, whom Russia said were "in the battle formations of terrorist groups.”
As tensions mounted in Idlib, Russia and Turkey - that are supporting the opposite sides to the Syria conflict - agreed on a ceasefire, under which their forces conduct joint patrols along the M4 highway linking Syria’s east and west, and establish a security corridor on either side of it.  
Turkey began its cross-border military operations in Syria with the declared aim of eliminating Syrian Kurdish militants of the People’s Protection Units (YPG), which Ankara regards as a terrorist organization tied to the Kurdistan Workers’ Party (PKK).
However, it has since occupied areas in northern Syria which Damascus says are in flagrant violation of its sovereignty.
