NATO: Afghan Rampage Won't Affect Pullout Timeline NATO and member countries say the slaying of 16 civilians in southern Afghanistan is a blow to the alliance's efforts to cultivate trust, but that it will not affect the timeline to hand over security operations by the end of 2014.

A U.S. service member walked out of a base in southern Afghanistan before dawn Sunday and started shooting Afghan civilians, according to villagers and Afghan and NATO officials. Villagers showed an Associated Press photographer 15 bodies, including women and children, and alleged they were killed by the American.

Officials said the shooter, identified as a U.S. Army staff sergeant, acted alone after leaving his base in southern Afghanistan. He was in custody at a NATO base in Afghanistan. Canada's Defense Minister Peter MacKay says NATO's "work will not be deterred by a random and cowardly act of violence."
