In a statement released Sunday by the White House, Obama said, “This incident is tragic and shocking, and does not represent the exceptional character of our military and the respect that the United States has for the people of Afghanistan.”
Panetta said a full investigation was under way.
The shootings come at a particularly sensitive and critical time for the US, just as violence over the burning of Muslim holy books at a US base was starting to calm down. The killings could further fuel calls for a more rapid withdrawal of US troops from Afghanistan.
US officials said the service member was being detained in Kandahar and the military was treating at least five wounded. One US official said the soldier, an Army staff sergeant, was believed to have acted alone and said initial reports indicated he returned to the base after the shooting and turned himself in.
A US official said the suspect is a conventional soldier from Joint Base Lewis-McChord in Washington state.
Another US official said the sergeant is married and has two children. He served three tours in Iraq and had been serving his first deployment in Afghanistan since December.
He was assigned to support a special operations unit of either Green Berets or Navy SEALs engaged in a village stability operation. Such operations are among NATO’s best hopes for transitioning out of Afghanistan. They pair special operations troops with local villagers chosen by village elders to become essentially a sanctioned, armed neighborhood watch.
The officials spoke on condition of anonymity because the investigation is ongoing.
Gen. John Allen, the top US commander in Afghanistan, issued a statement pledging a “rapid and thorough investigation” into the shooting spree, and said the soldier will remain in US custody.
The destruction of Qur’ans in a fire pit used to burn garbage last month sparked violent protests that killed some 30 people. Six US service members were killed in attacks by Afghan security forces since that incident, which US officials have apologized for and said was accidental.
