Bin al-Shibh is also wanted by German courts; he had shared a Hamburg apartment with Mohamed Atta, the suspected ringleader of the September 11 hijackers. In 2005, the USA denied a German request for bin al-Shibh's extradition. In an earlier extradition and trial, Abdelghani Mzoudi, a 9/11 suspect, was acquitted of German charges.
