Turkish and Russian forces carried out their sixth joint patrol along a key highway in northwestern Syria on Tuesday, APA reports citing Anadolu Agency.
"Within the framework of TUR-RF Agreement/Protocol, the 6th TUR-RF Combined Land Patrol on M-4 Highway in Idlib was conducted with the participation of land and air elements," Turkey’s Defense Ministry said in a tweet.
The M4 highway, also known as the Aleppo-Al Hasakah road, is about 30 kilometers (19 miles) from Turkey's southern border.
Last month, Ankara and Moscow agreed on a protocol urging parties to "cease all military actions along the line of contact in the Idlib de-escalation area” starting on March 6.
