Free Syrian Army (FSA) in cooperation with Turkish forces have captured several villages close to Manbij, northern Syria, that were under control of the Kurdish-led Syrian Democratic Forces (SDF), Turkish Haber7 broadcaster reported Wednesday.

Axar.az reports that, the US-backed SDF predominately consists of Kurdish fighters, linked to the Kurdistan Workers' Party (PKK) outlawed in Turkey.

Earlier this week, Turkish President Recep Tayyip Erdogan urged PKK-affiliated Syria's Kurdish Democratic Union Party (PYD) and Kurdish People’s Protection Units (YPG) to leave Manbij.

The Euphrates Shield operation by Turkey and FSA fighters began on August 24, 2016. During the operation, the joint forces liberated the Syrian cities of Jarabulus and Al Bab. Erdogan said that the aim of the operation was to clear the region of terrorists and make it a safety zone for refugees.

Since 2011, Syria has been engulfed in a civil war, with government forces fighting against numerous opposition and terrorist groups, including al-Nusra Front and Daesh, banned in a range of countries, including Russia.
