Nato troops have shot dead an Afghan civilian who worked at a coalition base in the south-east of the country.
Troops returning to the base in Paktika province opened fire after a vehicle approached at high speed, Nato said.
The vehicle did not stop despite a warning shot, a statement said. "A disabling shot was subsequently fired, regrettably killing one civilian."
The Afghan worked at the base in Orgun. Nato vowed a shift in tactics last week after mounting civilian deaths in 2006.
