"In this On Location video, GlobalPost senior correspondent Tracey Shelton tells the story of Issa, Ahmed and Qasim in the days before, and then at the very moment, they are killed in their back-alley post on the front lines of Aleppo, Syria.GlobalPost originally published a series of seven stills taken from the raw video shot by Shelton. They depicted the four men at first laughing, then — in an instant — only one emerges from the cloud of smoke and debris. Now, more than a week later, the front line remains the same. New people have replaced the old as the battle continues with what seems like no end in sight."
