A Federal jury in New York found senior al-Qaeda member Sulaiman Abu Ghayth guilty of terrorism-related charges on Wednesday, including conspiracy to kill Americans. In video statements and speeches released after the September11 attacks, Abu Ghayth promised similar attacks against U.S. and Western targets.

Evidence presented during the three-week trial included a screen shot of a video from September 12, 2001, showing Abu Ghayth sitting beside Osama bin Laden and other al-Qaeda members, including Ayman al-Zawahiri, the current leader of the terrorist group. A videotaped statement broadcast a month later on al-Jazeera showed Abu Ghayth saying, “there are thousands of Muslim youths who are eager to die and that the aircraft storm will not stop.” He warned “Muslims in the United States and Britain, the children, and those who reject unjust U.S. policy not to travel by plane.”

Abu Ghayth testified about being summoned by bin Laden to an Afghanistan mountain cave just hours after the 9/11 attacks. Bin Laden acknowledged al-Qaeda’s responsibility and sought Abu Ghayth’s help “to deliver a message to the world.”

Abu Ghayth also tried to recruit terrorists from training camps and safe houses. The video messages sought not only to instill fear in Americans but also “drive more suicide terrorists to Al Qaeda,” prosecutor John P. Cronan said during the trial.

Abu Ghayth, who was married to bin Laden’s daughter, was captured and brought to the United States last year, where he was indicted on terrorism-related charges. He was convicted on three counts related to a conspiracy to kill Americans, to provide material support to terrorists, and for providing actual support. He faces a maximum of life in prison for the first count and a maximum of 15 years for the latter two counts.

“He was more than just Osama bin Laden’s propaganda minister,” Manhattan U.S. Attorney Preet Bharara said in a Justice Department press release. “Within hours after the devastating 9/11 attacks, Abu Ghayth was using his position in al Qaeda’s homicidal hierarchy to persuade others to pledge themselves to al Qaeda in the cause of murdering more Americans.”
