KABUL, Aug. 5 (Xinhua) -- NATO-led forces on Thursday night confirmed killing Afghan civilians during an operation in eastern Afghanistan one day earlier.
During a joint operation with Afghan forces to hunt down Taliban leaders in Sherzad district of Nangarhar province Wednesday night, Coalition forces came under attack by insurgents and civilians were killed in the ensuing firefight, said a statement issued by the International Security Assistance Forces ( ISAF) on Thursday.
"Following information received from provincial and local Nangarhar officials, it appears that between four and a dozen or more civilians were killed," it said.
The statement also said 15 to 20 insurgents, including two senior Taliban leaders were killed in the operation. The joint forces called in air cover as they continued to take fire from insurgents when they were leaving the area.
Rear Admiral Greg Smith, ISAF director of communication, said coalition forces deeply regret the deaths of civilians and will work with the Afghan government to probe into the incident.
