(CNN) – Najah al-Hamid ripped open her black abaya, almost hysterical in her relief as she and her children threw themselves at the feet of the Syrian Democratic Forces (SDF), the Kurdish-majority militia that expelled ISIS from Raqqa. US-backed forces captured ISIS’ former de facto capital two weeks ago. After three years under the extremist group’s rule, and months of shelling in the campaign to oust the fighters, it is a miracle that the al-Hamid family are still alive. In the last days of the battle for Raqqa, an airstrike hit the five-story building they were living in.
