NATO says Afghan and coalition forces have killed more than 50 insurgents during a military operation in eastern Afghanistan.

The coalition said Friday the fighting occurred in Paktika province's Sar Rawza district during a clearance of a Haqqani network encampment. The network is affiliated with al-Qaida and the Taliban.

NATO said the site was a area where insurgents moved foreign fighters into the country for use in attacks across Afghanistan.

The coalition says disenfranchised insurgents had notified them of the camp's location. Officials said no civilians were harmed in the raid.
