Prosecutors contend he was a top-tier member of al-Qaida and knew of various terrorist plots.On Monday, prosecutors played two videos from October 2001 in which Abu Ghaith, a Kuwaiti and son in law of Osama bin Laden, is seen warning of further attacks in the wake of 9/11."There are thousands of young Muslims who look forward to die for the sake of Allah," Abu Ghaith said in one video. "The storm of airplanes will not stop."At another point, Abu Ghaith warns Muslims "not to board aircraft and we advise them not to live in high rises and tall buildings."
