A recent terror operation involving parcel bombs on UPS and FedEx flights cost just $4,200, according to a report in a magazine that analysts say is published by al Qaeda’s branch in Yemen. The article reports al Qaeda in the Arabian Peninsula’s claim of responsibility for the October plot to ship bombs disguised as printer components on cargo planes.
    The magazine also reports a controversial claim of responsibility for the September 3 crash of a UPS flight in Dubai, United Arab Emirates, which killed the two crew members. No evidence has surfaced of an explosion aboard the UPS cargo plane that crashed in September, officials in the United Arab Emirates have said. But authorities there have also said they are seriously looking into AQAP’s claim.
