The SDF, with the global anti-ISIS coalition advanced on the al-Baghuz axis, announced Kino Gabriel, spokesperson for the force, on Thursday evening.
Al-Baghuz is located on the Euphrates River near the Iraqi border in Deir ez-Zor province. It is one of a string of villages and towns along the river, the largest of which is Hajin.
Clashes “continue at a violent pace” along the eastern bank of the Euphrates, the Syrian Observatory for Human Rights reported on Thursday.
Coalition warplanes struck the area, in addition to artillery shelling, the UK-based conflict monitor added, saying that casualties occurred on both sides.
On Tuesday, the SDF announced the final phase of its operations against ISIS in eastern Deir ez-Zor province.
