Kabul, Afghanistan (CNN) -- Two NATO-led soldiers died in a friendly fire incident in southern Afghanistan, and a civilian was killed in an accident with a coalition convoy in the Afghan capital, NATO's International Security Assistance Force said.
An ISAF Joint Command incident assessment team is looking into the troop deaths, which occurred Wednesday. There were no details about what happened, and the precise location of the incident was not available.
ISAF said it plans to "determine the circumstances" of the friendly fire, the term for troops killing or injuring their allies or comrades.
In Kabul, the nation's capital, the civilian was killed and two others were injured when one of the three ISAF vehicles in the convoy "accidentally struck some civilians who were in the road," ISAF said.
"A nearby ISAF patrol provided a security cordon while first aid was administered." The injured were taken to a medical facility, the statement said, adding that no shots were fired by ISAF members.
The ISAF is the NATO-led mission helping the Afghan government in stabilizing the country and establishing security.
