US spokesman: Gunman in fatal Afghan attack was in uniform

A Pentagon spokesman says the gunman who killed three American contractors at the Kabul airport was in an Afghan uniform and was subsequently killed.
The spokesman, Rear Adm John Kirby, said Friday that the attack that killed three civilian aircraft mechanics is under investigation.
Earlier today, a Taliban spokesman in Afghanistan said the shooter was a Taliban fighter who had infiltrated the ranks of Afghan security forces to stage the attack and was wearing an Afghan police uniform.
Kirby said the US has no information to confirm or deny a Taliban role in the attack.
