SYDNEY  - A former Qantas worker found guilty of producing a do-it-yourself jihad manual had his conviction reinstated by Australia’s High Court Friday, with judges ruling he had extremist intentions. Lebanese-born Belal Khazaal, an ex-Qantas cabin cleaner, was jailed for 12 years in 2009 over the Arabic-language handbook, which included how-to guides on bomb-making, assassinations, kidnappings and shooting down planes. The 110-page “Provisions of the Rules of Jihad: Short Judicial Rulings and Organisational Instructions for Fighters and Mujahideen Against Infidels” named ex-US president George W. Bush and his CIA chief George Tenet as targets.
