U.S. Received Early Warning On Qaeda Plot.

WASHINGTON -- Saudi intelligence officials warned the United States in early October that Al Qaeda's affiliate in Yemen was planning a terrorist attack using one or more aircraft, three weeks before a plot to send parcel bombs on cargo planes was foiled at the last minute, American and European officials said Friday. The Saudi warning came days after American officials intercepted several packages in mid-September that contained books, papers, CDs and other household items shipped to Chicago from Yemen. The Americans considered the possibility that those parcels might be a test run for a terrorist attack. [ABSTRACT FROM AUTHOR]
