Gen. John Allen, the top U.S. commander in Afghanistan, tells Wolf Blitzer the U.S. soldier who allegedly killed 16 Afghan civilians acted alone.
"This is under investigation" he said, "but this appears it was an action of a single soldier."
In the exclusive interview on "The Situation Room," Allen confirmed the U.S. military is taking the lead on the investigation.
"We will certainly keep the Afghan government informed throughout this investigation," he explained, "but this individual will be investigated and the outcome will be in accordance with U.S. law."
Allen offered his sincere condolences to the victims, their families and the Afghan people.
"This is tremendously regrettable. We are investigating it aggressively and we will hold the individual accountable should the evidence point to his culpability here."
