KABUL - Afghan President Hamid Karzai on Tuesday condemned a NATO operation that he said killed four children in the country's east, a claim the coalition said was possible.
The operation took place in the Baraki Barak district of Logar province on Saturday, a statement released by Karzai's office said, adding: "It resulted in the killing of four innocent children" who were tending to livestock.
Civilian casualties have been a major source of friction between Karzai's government and the US-led NATO forces in Afghanistan.
"Despite repeated pledges by NATO to avoid civilian casualties, innocent lives, including children, are still being lost," Karzai said in the statement.
A spokeswoman for NATO's International Security Assistance Force (ISAF) said it was aware of possible ISAF-related civilian casualties from the October 20 operation.
