There was only one. Afghan villagers who escaped a March massacre in an Afghan village said they saw only one U.S. soldier during the attack. Army Staff Sgt. Robert Bales, accused of killing 16 villagers, acted with “chilling premeditation,” government prosecutors have said. They are seeking the death penalty for what they say involved two attacks on one bloody evening in March. The three witnesses Saturday testified at the hearing in Washington state via a video link from Kandahar Airfield in Afghanistan.
