The attack on Turkish soldiers marks the country's first reported casualties since a ceasefire began earlier this month.
The joint patrol in Syria's Idlib region was the result of a recent agreement between Ankara and Moscow on a ceasefire in Idlib province.
First Turkish-Russian joint patrol on M4 highway in Idlib to be conducted on March 15, says Turkish defence minister.
Defence Minister Hulusi Akar says "we are working to start a joint patrol [with Russia] along M-4 highway" of Idlib from March 15.
"If we reach an agreement by March 26 when there will be an EU leaders' summit, this issue will come on to the agenda of this meeting," Foreign Minister Mevlut Cavusoglu said.
The fighting came to a halt soon after the two powers signed a ceasefire deal in Moscow, but what are its key takeaways?
Cities and towns along the critical highway linking Damascus with Aleppo have become sites of brutal destruction at the hands of the Syrian regime.
Securing critical positions next to Turkey’s border, Turkish Armed Forces and their allies were quick to gain the upper hand in several YPG-occupied areas of northern Syria.
