On January 20, Ankara, jointly with the opposition Free Syrian Army forces, launched Operation Olive Branch in Afrin in order to "clear" Turkey's Syrian border from the terrorist threat.
"The [Turkish] Armed Forces have already established control over approximately half of the Afrin territory, where the Olive Branch operation is being held," Bekir Bozdag told reporters.
Earlier in the day, the General Staff of the Turkish Armed Forces said that the Turkish forces had killed or captured 2,777 militants of the Kurdish People's Protection Units (YPG), the Democratic Union Party (PYD), and the Daesh* terrorist group since the start of Operation Olive Branch.
Damascus has condemned the operation as a violation of Syria's sovereignty.
*Daesh (also known as ISIS/ISIL/IS) is a terrorist group banned in Russia
