A Yemeni prisoner watched an Al Qaeda recruiting video with his Guantanamo interrogator and proudly admitted producing the work, the interrogator testified in the US war crimes court. "He considered it one of the best propaganda videos Al Qaeda has to date," former FBI special agent Ali Soufan testified in the US war crimes trial of defendant Ali Hamza al Bahlul. Osama bin Laden was so impressed with the video that he promoted Bahlul to become his media secretary, the FBI agent quoted Bahlul as telling him. Bahlul is on trial at the US naval base in Cuba, on charges of conspiring with al Qaeda to attack civilians, soliciting to commit murder and providing material support for terrorism.
