In a hospital in northeastern Syria, a nurse tends to a Kurdish fighter recovering from burns to his face sustained in battle against advancing Turkish troops. “My dimples used to be like yours, but I lost one,” Suleiman Qahraman tells the nurse, smiling timidly to avoid hurting his scorched face too much. The invasion has killed more than 250 fighters of the Kurdish-led Syrian Democratic Forces (SDF) and wounded many more, according to Britain-based war monitor, the Syrian Observatory for Human Rights.
