(CNN) -- Three Afghan police officers were accidentally killed in an airstrike and a bomb killed five Afghan civilians in separate incidents in northern Afghanistan, NATO's International Security Assistance Force said on Saturday.
The airstrike incident, which occurred on Friday in Jowzjan province, began when insurgents shot at Afghan security forces, and the troops asked for air support.
An air weapons team consisting of two helicopters launched a hellfire missile and fired 30 mm rounds "toward an identified firing position".
The service members later found the three dead police and other wounded officers. ISAF dispatched a team to the region to investigate.
In the other incident, an improvised explosive device attack killed five Afghan civilians and wounded two other people on Saturday. One of those killed was a leader of the Arkabi, a local tribal militia. CNN
