NATO acknowledged Sunday that its troops killed five Afghans in a botched nighttime raid in February - after initially saying the civilians may have been victims of an "honor killing."
Even though civilian casualties at the hands of NATO troops have fallen off in recent months, such incidents have strained relationship between Afghanistan and the Western nations that make up the International Security Assistance Force.
At the time of the February 12 incident, NATO said its troops went to a compound in the village of Khatabeh in the Paktia province, believing it to be a militant hideout.
A firefight ensued and several insurgents died, NATO said at the time.

Military officials from NATO and its 28 member states descended on Washington last week for a series of discussions about rethinking how the alliance should transform itself in an era when its scope has expanded beyond traditional Cold War boundaries.
The seminar was hosted by former Secretary of State Madeleine Albright, who is chairing a group of experts appointed by the NATO secretary-general to recommend a new "Strategic Concept" for the alliance, governing how it perceives and responds to threats.
The group heard from some pretty heavy hitters: U.S. Secretary of Defense Robert Gates and Secretary of State Hillary Clinton, and NATO Secretary-General Anders Fogh Rasmussen, all of whom aptly acknowledged the alliance is facing a new strategic landscape with new enemies, ideologies and battle tactics that threaten its collective security.
