Italian and US authorities monitor an Italian cell of extremists linked to al-Qaeda (see Early 2000-2001) while its members discuss the use of a chemical weapon, but the cell does not appear to be able to make the weapon work. In phone conversations overheard by Italian intelligence operatives, Islamist extremists Sami Ben Khemais, Mohammed Ben Heni Lased, and others discuss the best way to transport chemicals—disguised as cans of tomatoes—and how to make a bomb out of a pressure cooker and a tape player. Ben Khemais also refers to a drug, for which a Libyan chemistry professor has a formula, but, although making the drug is supposedly easy, Ben Khemais cannot do it. He also suggests asking the Russian mafia for a chemical weapon, and refers to one man as “the sheik,” possibly meaning Osama bin Laden. However, despite his plans, no attacks are actually carried out. The Chicago Tribune will later comment, “Most of the talk is inconclusive, and, at times, Ben Khemais and his associates sound more like al-Qaeda wannabes than the calculating criminals as anti-terrorist investigators describe them.” [Chicago Tribune, 10/22/2001]
