An world-reknowned elite group of Native American trackers used by the U.S. Customs to hunt down Mexican drug and people smugglers reportedly is joining the hunt for terrorists crossing Afghanistan’s borders, where Usama bin Laden has been known to hide.

The Shadow Wolves unit, recruited from tribes including the Navajo, Sioux, Lakota and Apache, which patrols a 76-mile stretch of Arizona-Mexico border, is being sent to areas along the Afghan border to teach local units the traditional method called "cutting sign" of finding and following clues on the barren landscape, London's Sunday Times reported.

The Pentagon and the State Department, however, could not confirm the report the report to FOXNews.com, according to a Pentagon official.

The Shadow Wolves were expected to teach local border units ancestral sign-reading methods called "cutting sign," which include detecting twigs broken by humans, hair caught on a branch and how to determine how long a sliver of food may have lain in the dirt.

The unit was founded in the early 1970s to stem the flow of marijuana into the United States from Mexico and has located people smugglers across hundreds of square miles of the Tohono O’odham tribal reservation southwest of Tucson, Ariz.
