From Syria’s City of Homs, Shattered by War, one of 28 photos. Forces loyal to Syria’s President Bashar al-Assad walk in a street in old Homs city on May 8, 2014. Syrian forces took full control of Homs last week, a city once vibrant with pro-democracy crowds but now associated with images of ruin that epitomize the brutality of Syria’s civil war. After holding the Old City of Homs for nearly two years, close to 1,200 rebel fighters boarded buses which took them out of the “capital of the revolution” in convoys on Wednesday and Thursday, activists said. They were driven to rebel-held territory outside the city under a deal agreed between the insurgents and forces loyal to President Bashar al-Assad. (Reuters/Khaled al-Hariri)
