Turkish and Russian troops began their third joint ground patrols in northern Syria as part of an agreed-upon deal, according to Turkey’s National Defense Ministry on Friday.

Axar.az reports citing Hurriyet that the patrols will be carried out in Qamishli and Derik cities, east of the Euphrates, which were cleared of terrorists by Turkey.

"Within the framework of the agreement reached with the Russian Federation in Sochi on Oct. 22, 2019; the third joint land patrol began with the participation of Turkish and Russian military elements and UAVs in the region between Kamisli and Derik east of Euphrates," the ministry said in a tweet, using another spelling for Qamishli.

The first joint ground patrol which lasted for four hours was completed on Nov. 1. It took place 40 kilometers (25 miles) east of Ras al-Ayn and 30 km (18.6 mi) west of Qamishli city.

On Nov. 5, the two countries conducted the second joint ground patrols which lasted two hours east of Ayn al-Arab and west of Tal Abyad districts.

Ras al-Ayn and Tal Abyad were cleared of terrorists during Turkey’s Operation Peace Spring -- launched on Oct. 9 to eliminate terrorists from northern Syria east of the Euphrates River in order to secure Turkey’s borders, aid in the safe return of Syrian refugees and ensure Syria’s territorial integrity.
