Abu Ghaith, a 48-year-old Kuwaiti and son-in-law of Osama bin Laden, is on trial in Manhattan federal court for conspiring to kill Americans and providing material support to al-Qaeda.
During the session, prosecutors played two videos from October 2001.
“There are thousands of young Muslims who look forward to die for the sake of Allah,” Abu Ghaith said in one video.
“The storm shall not lessen especially the storm of the airplanes,” he shouted in one of the clips.
At one point, Abu Ghaith warns Muslims “not to board aircraft and we advise them not to live in high rises and tall buildings.” Prosecutors allege that Abu Ghaith was a top-tier member of al-Qaeda and knew of various plots.
