A third potential responder from a counter-terror force stationed in Europe says components of AFICOM -- the military's Africa Command based in Stuttgart, Germany -- were working on course of action during the assault. But no plan was put to use.
"Forces were positioned after the fact but not much good to those that needed it," the military source told CBS News.
"The response process was isolated at the most senior level," says an official referring to top officials in the executive branch. "My fellow counterterrorism professionals and I (were) not consulted."
