A Moroccan convicted of belonging to a terrorist cell that included three Sept. 11 hijackers was freed from prison Tuesday after a federal court ruled he shouldn't be jailed with appeals still pending. A statement by Germany's Federal Constitutional Court said the lower court had been wrong to order el Motassadeq returned to custody because appeals by both the defense and prosecutors were still pending. Mounir el Motassadeq, 31, was sentenced to seven years in prison in August by a court in Hamburg. In 2003, he became the first person anywhere to be convicted in connection with the Sept. 11 attacks when he was found guilty of membership in a terrorist organization. The Moroccan acknowledges he was close to the hijackers but insists he knew nothing of their plans. Defense lawyers criticized the lack of direct testimony from witnesses such as Ramzi Binalshibh, a key Sept. 11 suspect held by the U.S.
