NEW: Los Angeles Times publishes the photos at 7:30 a.m. Los Angeles (CNN) -- A slew of officials from NATO's International Security Assistance Force in Afghanistan and the U.S. military issued strong condemnations Wednesday as the Los Angeles Times published photos of U.S. troops posing with what the newspaper said are the bodies of suicide bombers. Gen. John Allen, the ISAF commander, "strongly condemned" the photos published by the Los Angeles Times. A U.S. soldier released the photos to the paper "to draw attention to the safety risk of a breakdown in leadership and discipline," the Times said. The military said an investigation is underway. The article published on the paper's website at 7:30 a.m. ET has two photos. One shows a member of the military in front of what appears to be the body of an insurgent. The photo shows the insurgent's head and what may be his hand on the soldier's shoulder. Another soldier appears to be looking down at the body. "A soldier from the Army's 82nd Airborne Division with the body of an Afghan insurgent killed while trying to plant a roadside bomb," the caption reads. The photo is one of 18 provided to The Times of U.S. soldiers posing with corpses. The second photo shows a group of people, including some American soldiers, standing above a mangled body with its two legs up in the air. One U.S. soldier who is smiling and giving a double thumbs-up, while another is smiling at the camera as well. That photo is not captioned. In the article, Times Editor Davan Maharaj said, "After careful consideration, we decided that publishing a small but representative selection of the photos would fulfill our obligation to readers to report vigorously and impartially on all aspects of the American mission in Afghanistan, including the allegation that the images reflect a breakdown in unit discipline that was endangering U.S. troops." A month later, ISAF personnel at Bagram Air Base improperly disposed of Islamic religious materials, including Qurans, in what U.S. officials described as an unintentional error.
