Ahmed Ibrahim Al Haznawi is suspected as one of the hijackers of United Airlines flight 93 as part of the September 11, 2001 Terrorist Attack.
Ahmed Al Haznawi appeared on a videotape from Al-Qaida that was aired on Al Jazeera on April 16, 2002. He talked about his plans to bring our the "bloodied message" to the world.
Al-Haznawi once sought treatment at Holy Cross Hospital in Fort Lauderdale, Florida for a "skin lesion" . Some allege that this caused by cutaneous anthrax, which would show, according to them, that those responsible for the September 11 attacks also committed the 2001 anthrax attacks.
