This is the second "green-on-blue attack" this year, which are assaults on foreign troops by members of the Afghan security forces or a gunman wearing an Afghan military uniform acting individually or as part of an organization.
The shootout occurred in the city of Jalalabad after officials met with the governor of the Nangarhar Province. One Afghan soldier was killed and another was injured when U.S. troops returned fire, but it is unclear if the Afghan soldier who opened fire was among them.
