"The Kremlin is concerned by the growing tension on the Syrian-Turkish border," Peskov said in a conference call with reporters.
"In general, Russia deems it unacceptable that Turkish artillery conducts cross-border shelling of the Syrian territory," Peskov stressed.
On February 13, Turkish artillery began shelling positions held by the Kurdish People's Protection Units (YPG), a Kurdish group with links to the Syrian Kurdish Democratic Union Party (PYD), in Syria's Aleppo Province.
Turkey believes that the Kurds in Syria have ties to the Kurdistan Workers’ Party (PKK) militant group, considered a terrorist organization by Ankara, which fights for Kurdish independence from Turkey.
On Friday, US President Barack Obama held a telephone conversation with Turkish President Recep Tayyip Erdogan, urging Ankara to exercise restraint and cease artillery strikes in the area.
