Ten civilians died in a NATO airstrike in the eastern province of Kunar, Afghan officials said Wednesday, while the International Security Assistance Force insisted that the only fatalities were two Taliban fighters.

"An air attack by NATO killed 10 civilians," including four women and five children, provincial Gov. Fazula Wahidi told Tolo television.

ISAF, however, said in a statement that only "two insurgents" perished in Tuesday night's operation in the Ghaziabad district, which was carried out jointly with Afghan forces.

The attack "was precise," the NATO-led ISAF said, adding that a subsequent evaluation concluded there was no harm to civilians or civilian property.

A Taliban spokesman told the AIP news agency that three rebels were killed along with the 10 civilians mentioned by the Kunar governor.

Zabiula Muyahid also claimed that five NATO/Afghan troops died and three others were wounded.

Civilian fatalities are a major cause of friction between the Afghan government and NATO, which is carrying out a gradual withdrawal that calls for foreign troops to leave Afghanistan by the end of 2014. EFE
