BERLIN, Aug. 9 (Xinhuanet) -- A Moroccan student suspected of being an accomplice in the September 11 attacks has demanded the court drop all charges against him, his lawyer said Monday.

    On the eve of the retrial of Mounir El Motassadeq in the Hamburg State Court, a statement issued by his lawyer said that "we intend to file a request for all charges to be dismissed on thebasis of lack of evidence."

    Defense attorney Josef Graessle-Muenscher said that his client would also withhold all testimony when retrial proceedings begin Tuesday.

    Motassadeq was studying in Hamburg where he became a friend ofMohammed Atta, also a foreign student and the pilot who flew one of the two hijacked planes into the World Trade Center in New York.

    Early last year, the Hamburg State Court sentenced the 30-year-old Motassadeq to 15 years in prison on charges of aiding the September 11 attacks.

    But the German Constitutional Court ruled this spring that Motassadeq should be retried because prosecutors had failed to provide some key evidence.

    German federal prosecutors have admitted that they can not provide the evidence because of Washington's rejection to supply them with testimonies from alleged terrorists now being held in the United States. Enditem
