The men surround the woman as she stands in a hole dug into the stony ground, only her head pokes above the surface. Then they begin to pick up rocks and hurl them at her again and again from close range.
Her agonized cries grow louder as the barrage of stones intensifies.
The barbaric killing took place in a Taliban-controlled village in central Afghanistan last week, according to the provincial governor. Video of it, apparently filmed on a cell phone, has circulated on social media.
The 19-year-old woman, identified as Rokhshana, had been forced to marry against her will and recently fled with another man, said Seema Joyenda, the governor of Ghor province. The couple were caught after two days, and the Taliban leader of the village ordered that Rokhshana be stoned to death for adultery, Joyenda said.
