The Russian military on Thursday blamed U.S. troops for a collision of Russian and U.S. military vehicles in Syria’s northeast. U.S. officials said Wednesday that a Russian vehicle sideswiped a light-armored U.S. military vehicle, injuring four Americans, while two Russian helicopters flew overhead, one as close as 20 meters (70 feet) from the U.S. vehicle. U.S. National Security Council spokesman John Ullyot said in a statement that a Russian vehicle struck the American vehicle near Dayrick, in northeast Syria.
