THE Kurdish-dominated Syrian Democratic Forces (SDF) captured the last town held by the Islamic State (Isis) terror group today.

The fall of Hajin means no sizeable settlement is controlled by Isis any longer, although it still holds some villages in the area which adjoins Iraq. At its peak in 2014, the jihadist army controlled over 40,000 square miles of territory, an area larger than Scotland.

People’s Protection Unit (YPG) spokesman Nuri Mahmud said that “intense fighting” was continuing against Isis around Hajin. The YPG forms the biggest component of the SDF, which has benefited from embedded US military advisers and aerial support.

But the threat of a major Turkish assault hangs over the group. Having vowed to attack Syrian Kurds “within days” on Wednesday, Turkish President Recep Tayyip Erdogan threatened a direct assault on Manbij yesterday, which would bring Turkish and US forces into direct conflict.

The SDF called for solidarity from Syrians of all groups in the event of a renewed Turkish invasion of the country.
