After Turkish forces took the previously ISIS-held town of al-Bab on February 23, clashes have intensified in northern Syria between Turkish forces and local proxies occupying an enclave in northern Syria, on one hand, and the Syrian Democratic Forces (SDF) on the other.
The SDF is an alliance of progressive armed groups — the largest of which are Kurdish-based Peoples Defence Units (YPG) and Women’s Defence Units (YPJ) — that is subordinate to the grassroots democratic structures of the Democratic Federation of North Syria.
