Turkish security forces hit PYD/PKK in Syria's Afrin
On Saturday, President Recep Tayyip Erdogan announced that a ground operation in Syria's Afrin had been launched.
Addressing the ruling Justice and Development (AK) Party's sixth annual provincial congress in western city of Kutahya, Erdogan said an operation in Manbij in Syria will come after Afrin because "promises made to Turkey have not been kept."
Military vehicles and work machines sent to reinforce the troops stationed at the Syrian border were already in Turkey's Hatay province.
Turkey has long protested the U.S. support for the PYD -- the Syrian offshoot of the terrorist PKK -- and its military wing the YPG.
Washington has called the terrorist group a "reliable ally" in its fight against Daesh in Syria even though its mother organization, the PKK, is listed as a terrorist group by Turkey, the U.S., and the EU, having waged a terror campaign against Turkey for more than 30 years, killing nearly 40,000 people.
