Kabul, Afghanistan -- A shot rings out, but the burqa-clad woman sitting on the rocky ground does not respond. The man pointing a rifle at her from a few feet away lets loose another round, but still there is no reaction. He fires a third shot, and finally the woman slumps backwards. But the man fires another shot. And another. And another. Nine shots in all. Around him, dozens of men on a hillside cheer: "God is great!" Officials in Afghanistan, where the amateur video was filmed, believe the woman was executed because two Taliban commanders had a dispute over her, according to the governor of the province where the killing took place.
