"Coalition forces killed two armed militants, one female civilian, and provided medical care to four more civilians during an operation early Thursday morning," it said, without identifying the casualties.
The wounded were paid compensation, the coalition force said.
Civilians are often caught up in Afghanistan's conflict as international and Afghan troops battle extremist insurgents, including those from the Taliban who were in government between 1996 and 2001. Afghan and coalition forces meanwhile killed 17 insurgents in air strikes in the southern province of Kandahar late Saturday, another statement said. The operation was launched against a "known insurgent safe haven," it said.
It appeared to be the same operation that was reported separately by Afghan police, who said 11 Taliban militants were killed.
And the government of the central province of Ghazni said its forces had thwarted a Taliban attack on the Ab Band district administration centre late Saturday, killing eight gunmen. The Nato-led coalition also announced Sunday it had killed a "senior Taliban commander" in a targeted operation last week in southern Helmand province, a stronghold of the militants.
