An Arabic-language biography of Osama Bin-Laden, entitled \"The Warrior from Mecca,\" has become a best-seller in the Arab sector. Dozens of copies have been sold in the past week alone, up from absolutely zero sales before the World Trade Center and Pentagon attacks. Written by a Saudi reporter and published last year in London, the book says that according to most estimates, Bin Laden acquired non-conventional weapons from Eastern Europe in the 1980\'s and that he was on good terms with the terrorist Carlos.
