KABUL, Afghanistan (Aug. 30, 2011) – A combined Afghan and coalition security force killed more than 10 insurgents and detained another nine during separate, overnight searches targeting a Haqqani network attack cell in eastern Afghanistan. 

The targets of the searches were several Haqqani facilitators responsible for planning an imminent attack on Kabul city under direction from Haqqani leaders based in Pakistan. Tips from local citizens indicated the insurgents’ locations and that they were organizing the attack to happen in the next few weeks.
 
In Nerkh district, Wardak province, while initiating the search, the force was attacked by multiple groups of insurgents armed with rocket propelled grenades. Responding to the attacks, the force returned fire, killing several.
