U.S.-backed SDF offensive aims at clearing the jihadists from Deir Ezzor province

U.S.-backed fighters launched a new offensive on Saturday to oust the Islamic State group from swathes of Syria’s eastern Deir Ezzor province, a top commander announced.

The Syrian Democratic Forces (SDF) are already fighting for IS’s de facto capital in Raqa, and they will now aim to clear the jihadists from territory east of the Euphrates River, said Ahmad Abu Khawlah.

Mr. Abu Khawlah, who heads the SDF’s Deir Ezzor Military Council, read the statement at a press conference inHasakeh province.

He said his forces had begun fighting to push IS out of remaining territory in Hasakeh province and further south in Deir Ezzor. We are taking the first step to liberate territory east of the Euphrates River in Deir Ezzor,” Mr. Abu Khawlah said.

Since 2014, IS has held swathes of the eastern province, which border Iraq, and about 60% of the provincial capital, Deir Ezzor city. Saturday’s announcement came as Russia-backed Syrian regime forces were waging a separate offensive to oust IS from Deir Ezzor city.

“We are not coordinating with the regime or with Russia. We are coordinating with the international coalition,” said the SDF commander. He said the coalition air strikes had already helped them advance “around 30 kilometres” in their first clashes.
