ANKARA, Nov 6, (APP/AFP) – The top US general Joseph Dunford on Sunday made a previously unannounced visit to Ankara for talks with his Turkish counterpart, the army said, as Kurdish-Arab forces launched an operation to capture the jihadist bastion of Raqa in Syria. The chairman of the US joint chiefs of staff was to hold talks with his Turkish counterpart Hulusi Akar, the army said, without giving further details. The Kurdish-Arab force leading the fight to take the Syrian city of Raqa from the control of Islamic State jihadists had said earlier that Washington had agreed Turkey would play no role in the offensive. Ankara had previously expressed alarm that the Kurdish-Arab Syrian Democratic Forces (SDF) were dominated by the Kurdish Peoples’ Protection Units (YPG) militia.
