"We leave behind the 39th day in our ‘Operation Olive Branch.’ Our soldiers continue to carry out the operation from land and air with utmost determination. Afrin has been surrounded by a crescent-like shape," Yildirim said Tuesday, as quoted by Hurriyet Daily News.
The prime minister added that within the course of the operation, Turkish troops backed by militias loyal to Ankara had been advancing in the region, while Turkish police units and forest guards had been ensuring order in the areas under the Turkish forces' control.
Ankara has been carrying out the operation dubbed Olive Branch since January 20, in the wake of the US announcement that a new border force largely dominated by the People's Protection Units (YPG), which Turkey considers to be terrorists, would be formed by Washington.
The Syrian government has strongly condemned the operation conducted by Turkey as an assault on the nation's sovereignty. Russia, in turn, has urged all parties to exercise restraint and called for respect of Syria's territorial integrity.
