KABUL Eight foreign troops from the NATO-led force in Afghanistan were killed in a shooting involving an Afghan Air Force pilot at the Afghan capital's airport on Wednesday.
The shooting follows a string of attacks by Afghan security forces against their NATO-led mentors carried out either by "rogue" soldiers or by uniformed insurgents.
Rapid recruitment into the Afghan security forces, which will be boosted to at least 305,000, has raised fears the Taliban have infiltrated sympathizers into the police and army.
Here is a list of "rogue" attacks:
