US-backed forces give IS 48 hours to leave Syria's Manbij
US-backed fighters on Thursday gave the Islamic State group 48 hours to leave the battleground Syrian town of Manbij, after US-led air strikes nearby killed scores reported to be civilians. Elsewhere, a monitor said at least 51 civilians were killed in bombing raids on rebel-held areas across Syria. The 48-hour ultimatum was issued by the Arab-Kurdish Syrian Democratic Forces (SDF), which is fighting IS with coalition air support.
