Arab ‘element’ withdraws from Raqqa Offensive- Doubting Ethnic Cleansing by Kurds?

This news, certainly, corroborates my earlier claims-Is the US going to reign the PKK/YPG militia in?I certainly don't think they will. How about You?

“The Raqqa offensive is on shaky footing now that a key Arab element—Thuwar ar-Raqqa—has withdrawn from the U.S.-backed Syrian Democratic Forces, “declaring Kurdish forces had broken an agreement to allow them to lead the charge” on the Islamic State group’s de facto HQ in Syria.The agreement was that the SDF would only provide logistical support for the operation,” Mahmoud Hadi, a Thuwar ar-Raqqa official, told the Middle East Eye Thursday. “Everything had been agreed beforehand, we even agreed which flags would be raised…and that the brigade would be in charge of the administrative and security management of the city afterwards. But what happened on the ground has unfortunately been the complete opposite to what we had agreed.”
