TOPSHOT-SYRIA-CONFLICT-RAQA

TOPSHOT - A picture taken on October 28, 2017, shows a fighter of the Syrian Democratic Forces (SDF) walking through an empty rubble-filled street surrounded by damaged buildings in the Syrian city of Raqa. The US-backed SDF took full control of Raqa on October 17, wrapping up an operation that lasted more than four months to capture a city that had been the inner sanctum of IS's now moribund "caliphate". Hundreds of thousands of people fled the city since 2014 and by the time the SDF retook it, Raqa had become a ghost town of collapsed buildings.
