A two-star American general was killed Tuesday after a shooter wearing an Afghan military uniform opened fire at a training facility in Kabul, U.S. officials told CNN's Jim Sciutto.
At least 15 coalition troops, including other Americans, were wounded in the attack at Camp Qargha, Sciutto was told.
Earlier the German military said one person was killed and 14 were injured. One of those wounded was a German brigadier general. The German military said the incident occurred during a "key leader" event.
The Afghan Defense Ministry described the shooter as a "terrorist" and said Afghan soldiers shot him dead.
NATO's International Security Assistance Force said the incident took place between local Afghan and ISAF troops.
In the past, people dressed as Afghan security forces have attacked coalition forces who have worked to thwart such violence.
