Coalition warplanes kill 20 Islamic State militants in Syria: Turkish army

United States-led coalition warplanes killed 20 Islamic State militants in Syria over the last 24 hours, the Turkish military said on Tuesday, nearly two months into a Turkey-backed rebel operation to drive the jihadists away from the border. Turkey pushed on with the Syrian operation as Iraqi forces launched a U.S.-backed offensive to expel Islamic State (IS) from the northern Iraqi city of Mosul. The 11 coalition air strikes in Syria targeted the areas of Kar Kalbayn, Ghuz, Hassajik and Tiltan
