President Tayyip Erdogan on Saturday said that if "the terrorists in Afrin do not surrender, then Turkey will destroy them."
Ankara considers the SNA and the Syrian Democratic Union party to be a branch of the Kurdistan Workers Party banned in Turkey. Over the past months, Erdogan has repeatedly spoken about the possibility of conducting a military operation against them in the Syrian canton of Afrin.
Earlier, Ankara has repeatedly condemned Washington for military support of the YPG, which Turkey considers a terrorist organization associated with the Kurdistan Workers Party banned in the country.
