DARBASIYAH, SYRIA  -  The creation of a so-called “safe zone” in north-eastern Syria has gotten off to good start, with US-backed Kurdish-led forces pulling back from a small, initial area along the Turkish border, a Syrian Kurdish official said — but calm can only prevail if Turkey also removes its troops. Ilham Ahmed, co-chair of the executive committee of the U.S-backed Syrian Democratic Council, said the understanding reached between Washington and Ankara last month, and in coordination with the Syrian Kurdish-led forces, constitutes a step toward starting a dialogue over mutual security concerns.
