A Tunisian suspected of heading Usama bin Laden's European logistics operations was convicted Friday, the first guilty verdict in Europe related to Al Qaeda since Sept. 11.

Essid Sami Ben Khemais, known as "the Saber," was convicted of the main charges — including criminal association with the intent to obtain and transport arms, explosives and chemicals — and was sentenced to five years in prison.

Three other Tunisians on trial with him, Belgacem Mohamed Ben Aouadi, Bouchoucha Mokhtar and Charaabi Tarek, were convicted on the same charges and sentenced to up to five years in prison.
