PHILADELPHIA - The self-described "Jihad Jane" who thought her blond hair and blue eyes would let her blend in as she sought to kill an artist in Sweden is a rare case of an American woman aiding in foreign terrorism and shows the evolution of the global threat, authorities say.

The suburban Philadelphia woman, Colleen R. LaRose, is accused in the indictment filed Tuesday of trying to recruit fighters, as well as agreeing to murder the artist, marry a terrorism suspect so he could move to Europe and martyr herself if necessary.
