BEIRUT, Lebanon — Suspected Russian raids killed 47 civilians in war-ravaged eastern Syria on Saturday, amid reports U.S. forces are building up an air base to bolster their fight against jihadists further north. Meanwhile, senior diplomats scrambled to resolve the key question of who will represent Syria’s opposition at crucial talks next week aimed at ending the nearly-five year war. In eastern Syria, the 47 civilians were killed in air strikes suspected to have been carried out by Russian warplanes on a jihadist-held village. The Syrian Observatory for Human Rights said nine children and two women were among the dead in Khasham, which is controlled by the Islamic State (IS) group. The village is in Syria’s oil-rich Deir Ezzor province, where IS has sought to advance in recent days despite a barrage of Russian and Syrian government air strikes. The week-long IS offensive on the provincial capital has left nearly 500 people dead and sparked fears of mass killings among the 200,000 people still living there.
IS declared a self-styled “caliphate” in 2014 across swathes of Syria and Iraq, imposing its ultra-conservative interpretation of Islamic law there. In Syria, it is under fire by the government and Damascus’s long-time ally Russia, as well as a U.S.-led coalition also battling the jihadists in Iraq. ‘Ready to be used’ To bolster their fight against the group, U.S. special forces deployed in Syria are building up an airbase in the northeast, sources told AFP on Saturday. A Syrian military source said nearly 100 “American experts” and Syrian Kurdish militia were almost done outfitting Rmeilan airfield in Hasakeh province. “The airbase will be used for helicopters and cargo planes. Its strip is now 2,700 meters (yards) long and is ready to be used by planes that will transport equipment and ammunition,” the source added. A security source in northeast Syria said “American special forces and advisers are using the Rmeilan airport as a base, from where helicopters are taking off towards the fronts.” The Pentagon said the U.S. had “not taken control” of any airfield in Syria. “There has been no change to the size of mission of the U.S. presence in Syria,” said U.S. Central Command spokesman Colonel Pat Ryder. “That being said, U.S. forces in Syria are consistently looking at ways to increase efficiency for logistics and personnel recovery support,” he said. In October, Washington authorized the deployment to Syria of up to 50 special operations troops to advise local forces battling IS. Syria’s conflict first erupted with anti-government protests in 2011 but has since morphed into a bloody, complicated war that has killed more than 260,000 people.
