Kabul, Afghanistan (CNN) -- A NATO raid left four civilians dead -- including two children -- in eastern Afghanistan, a district governor told CNN on Thursday.
The International Security Assistance Force said "there is credible evidence" that civilians were killed in the airstrike in Ghazni province.
"ISAF deeply regrets the loss of life and injuries, and is committed to a thorough and transparent review of this incident," the international alliance said in a statement.
It did not detail how many civilians were killed.
The airstrike occurred Wednesday.
The casualties came about after Afghan and coalition forces came under gunfire while patrolling the area, the international alliance said in a statement.
An air weapons team fired back, killing and injuring people, the statement said.
The wounded were taken to an International Security Assistance Force hospital and the coalition officials met with village elders to notify them.
The international alliance was formed under a U.N. mandate to bolster a secure environment and support the reconstruction of Afghanistan.
NATO took command in 2003.
