Robert Bales, the US soldier accused of killing 16 Afghans and injuring six others, could face the death penalty if found guilty of murder, the US Army says.
Staff Sgt. Robert Bales, 38, will face a court martial on murder and assault charges for a March attack on two villages in southern Afghanistan.
No date has been set for the trial, which will take place at Joint Base Lewis-McChord in Washington state.
No US service member has been executed in more than 50 years.
Seventeen victims were women or children, with most shot in the head.
