The Syrian armed forces, however, yet to confirm this information.

"Yes, this is true. Today the Syrian government army entered Afrin in order to defend the city from the Turkish Armed Forces and the Free Syrian Army jointly with the Kurdish forces of the YPG. The government forces have come to help the people of Afrin. We cannot report on the number of soldiers that entered Afrin. This is military information."

Meanwhile Turkish President Recep Tayyip Erdogan's spokesman Ibrahim Kalin said Tuesday that media reports about the Syrian pro-government troops’ entry in Afrin district are "black propaganda.”

"It is quite clear that the reports on the agreement between the regime and the YPG are black propaganda. However, this does not mean that there cannot be any secret and dirty bargaining there", Kalin said quoted by the Hurriyet newspaper as saying.

At the same time, according to Reuters information agency, Syrian state TV has reportedly shown a convoy, what it says are pro-government forces, entering Afrin.

On Monday, Syrian state television channel Ikhbariya reported that pro-Syrian government forces would enter Afrin area "within hours." At the same time, Damascus hasn't commented on the issue yet.

Turkey has been conducting the "Olive Branch" in Syria's Afrin since January 20, targeting the Kurdish YPG.

Damascus has firmly condemned the military campaign, calling it a violation of the country’s sovereignty.
