A German man arrested in France last week on suspicion of links to the Sept. 11, 2001 attacks on the United States is a top leader of the al Qaeda network, France's Interior Minister said Wednesday. Christian Ganczarski, 36, was arrested at Paris's Charles de Gaulle airport on June 2. "(Intelligence) services know that he is a top leader of al Qaeda, in contact with Osama bin Laden himself, and has been in Afghanistan and Bosnia," Interior Minister Nicolas Sarkozy told parliament.
