Now this isn't just a story of civilians mistakenly shot or killed in the crossfire, this is, by all accounts, a systematic slaughter of unarmed people by a single (??) rogue US Army soldier. And more than half of his victims were children.
In the pre-dawn hours of Sunday, a US soldier stationed at a base in Afghanistan's Kandahar province allegedly launched a single-handed gun attack on nearby Afghan villagers.
He is said to have broken into homes in two villages, Alkozai and Najeeban, both located about 500m (yds) from the base in Panjwai district.
By the end of the attack, 16 people, nine of them children, were dead and five wounded. Some of the bodies had been set on fire.
Some Afghan authorities are obviously asking to handle the soldier's trial themselves. And there are questions about whether or not the soldier truly acted alone.
So what should the US do here? What are the long-term implications?
