In one of the most iconic images yet to come out of Syria's civil war, a band of rebels in an outpost in Aleppo are captured in this video frame at the exact moment a tank shell slammed into them. The only survivor, in addition to the photographer, was the one in dark silhouette, closest to the camera. Global Post's Tracey Shelton said she was filming a feature on life on the frontlines of Aleppo, camping out with the men of Noor Den al-Zenke batallion, in a two-block stretch of backstreets that had formed the final line between government troops and opposition forces. The men had been warned a tank was approaching, and were grabbing their weapons when a shell hit.
