Kurdish Forces Announce IS Defeat in Eastern Syria by VOA News Kurdish forces in Syria announced Sunday that they had regained control of a key area east of the Euphrates river from Islamic State militants. The People's Protection Units (YPG) thanked Russian forces as well as the United States-led coalition for logistical and air support in retaking Deir al-Zour's eastern countryside. Speaking at a news conference Sunday, YPG's spokesperson Noureddine Mahmoud said that he hoped for more coordination with the two international powers. A day earlier, U.S. Defense Secretary Jim Mattis suggested the United States will move away from arming Syrian Kurdish fighters, as part of a wider shift from a military-led to a diplomatic-led approach in Syria. Last week, Turkey, which considers the YPG a terrorist organization, claimed that U.S. President Donald Trump said the U.S. would stop arming Kurdish fighters in Syria. The YPG, the backbone of the U.S.-backed Syrian Democratic Forces, bore the brunt of the fighting to clear IS forces from their self-proclaimed capital in Raqqa, Syria.
