Using e-mail, YouTube videos, phony travel documents and a burning desire to kill “or die trying,” a middle-aged American woman from Pennsylvania helped recruit a network for suicide attacks and other terrorist strikes in Europe and Asia, according to a federal grand jury indictment unsealed Tuesday.
