Thirty-three civilians mistaken for Taliban fighters have been killed by a NATO airstrike in southern Afghanistan, according to the government in Kabul.
A spokesman for the Interior Ministry said there were women and children among the dead and wounded.
He said troops from a joint NATO-Afghan unit on the border of Uruzgan and Dai Kondi became suspicious when they saw a number of civilian vehicles approaching them.
They called for air support, and the three mini-buses were bombed.
The incident was not part of Operation Moshtarak, a big push to clear Taliban fighters from neighbouring Helmand province.
The Afghan government condemned the killings.
The issue of civilian casualties has become a major cause of friction between the government in Kabul and the foreign forces in the country.
