Afghan soldiers killed in airstrike
A Nato airstrike has killed four Afghan soldiers in the country's south, mistaking them for militants, an Afghan military official said.
A spokesman for the country's defence ministry said the Afghan soldiers had left their base in Helmand province on Wednesday night for a patrol when they came under fire from Nato planes.
General Mohammad Zahir Azimi said Nato told the Afghan government that the coalition thought the men were militants.
A spokesman for Nato forces, Captain Ciro Parisi of the Italian army, said they have sent a team to investigate the incident.
