Today, Commander of U.S. forces in Afghanistan General John Campbell informed Congress that a U.S. military airstrike in Kunduz, Afghanistan, to support Afghan forces on the ground resulted in a mistaken attack on a Doctors Without Borders field hospital. Doctors Without Borders does important work all around the world, and the Department of Defense deeply regrets the loss of innocent lives that resulted from this tragic event. The investigation into how this could have happened is continuing, and we are fully supporting NATO and Afghanistan's concurrent investigations. We will complete our investigation as soon as possible and provide the facts as they become available. The U.S. military takes the greatest care in our operations to prevent the loss of innocent life, and when we make mistakes, we own up to them. That's exactly what we're doing right now. Through a full and transparent investigation, we will do everything we can to understand this tragic incident, learn from it, and hold people accountable as necessary.
