The Afghan defence ministry said on Thursday that a NATO air strike killed four Afghan soldiers in the country's south.
"Initial reports we have indicate that an air strike last night killed four Afghan National Army soldiers who were on a patrol mission in Musa Qala district," defence ministry spokesman General Mohammad Zahir Azimi said.
Musa Qala is a restive district in Helmand province, one of the main strongholds in the Taliban's nine-year insurgency against the western-backed Afghan government and US-led NATO troops.
