US-backed militias have completely taken Syria's Raqqa from IS, said the Syrian Observatory for Human Rights. The fall of Raqqa city, where IS staged euphoric parades after its string of lightning victories in 2014, is a potent symbol of the jihadist movement's collapsing fortunes. From the city, the group planned attacks abroad. The Syrian Democratic Forces (SDF), an alliance of Kurdish and Arab militias backed by a US-led international alliance, have been fighting IS inside Raqqa since June 2017.
