Dawn breaks to a daily chorus of artillery and mortar fire in two of humanity’s most ancient settlements that today are Syria’s two largest cities, Damascus and Aleppo. Projectiles rain on their rural peripheries, where opposition groups still fighting the regime of President Bashar al-Assad shelter in tunnels below mountains of rubble. Muezzins wake the faithful to prayer, and warplanes deliver the day’s first payloads just after 5:00 AM. The rebels respond with desultory mortar rounds fired at cities they once dreamed of ruling. In Damascus, their shells explode in the Christian neighborhoods closest to the eastern front lines. In Aleppo, artillery batters opposition bases along the western frontier with Idlib province. Both cities’ exhausted citizens have cause to fear for their country’s uncertain future.
