Video of the aftermath of a disputed incident involving American forces and the Taliban shows bloodied bodies of children laid out with other corpses, confirming international Red Cross findings at the two remote villages in western Afghanistan.
The US military does not contest that civilians died but called "extremely over-exaggerated" a report by an Afghan official that as many as 147 were killed.
Afghans blame aerial bombing Monday and Tuesday for the deaths and destruction. President Hamid Karzai said the airstrikes were "not acceptable" and said the government estimated the number of civilian deaths to be 125 to 130, according to an interview with CNN on Friday.
"We cannot justify in any manner, for whatever number of Taliban, for whatever number of significantly important terrorists, the accidental or otherwise loss of civilians," he was quoted as saying.
