Five American troops were killed on June 9th, 2014 during a security operation in southern Afghanistan, Pentagon Press Secretary Navy Rear Adm. John Kirby reported.
In a statement, Kirby said investigators are looking into the likelihood that friendly fire was the cause.
“Our thoughts and prayers are with the families of these fallen,” he added.
The incident occurred during a security operation when the U.S. service members’ unit came into contact with enemy forces, International Security Assistance Force officials said in a statement issued from the command’s headquarters in Kabul, Afghanistan.
“Tragically, there is the possibility that fratricide may have been involved,” the statement said. “The incident is under investigation. Our thoughts are with the families of those killed during this difficult time.”
