"Patrols by the Russian military police continued on routes ...in the Aleppo province, … in the Hasakah province", Borenkov said.
These patrols are part of the Russia-Turkey deal on the buffer zone in northern Syria.
Following talks between Russian President Vladimir Putin and Turkish President Recep Tayyip Erdogan, a Russian-Turkish memorandum was signed in October. The agreement includes a variety of patrol missions carried out by the Russian military contingent in Syria, Syrian border guards, and Turkish troops.
The document also stipulates conditions for the peaceful withdrawal of Kurdish militants in Syria to a distance of 30 kilometres (18.6 miles) from the border with Turkey.
