Mohammed Jamal Khalifa (Arabic: محمد جمال خليفه) (1 February 1957 – 31 January 2007) was a Saudi businessman from Jeddah who married one of Osama bin Laden's sisters.

[10] One example of his syphoning off of charitable funds, according to Newsweek, was his reporting to his "Saudi sponsors" that he had built 33 orphanages across the southern Philippines when in fact Khalifa had set up only one institution for orphans.

[11] What was left of the Benevolence International Corporation allegedly gave logistical support to terrorists,[12] and has been accused of assisting the 1993 World Trade Center bombing and the Bojinka plot (of Khalid Sheikh Mohammed, Ramzi Yousef to blow up 11 American jetliners killing 4,000 people in early 1995).

[2] Another organization founded by Khalifa, the International Relations and Information Center, has been called (by Zachary Abuza) the "primary funding mechanism" for the Bojinka plan.

[13] According to the Philippines National Security Advisor, Roilo Golez, Khalifa "built up the good will of the community through charity and then turned segments of the population into agents.

"[2] According to Rohan Gunaratna, Khalifa dispatched at least one Filipino youth to Tripoli, Libya, on an eight-month training course and on his return in 1990 urged him to join ASG.

[2] From the Philippines, he "established links with Islamists in Iraq, Jordan, Turkey, Russia, Malaysia, the UAE, Romania, Lebanon, Syria, Pakistan, Albania, the Netherlands and Morocco, enabling the ASG to develop relationships with terrorist groups" throughout the Middle East and Asia.

"Their most important source of leverage was the visas and jobs for several hundred thousand Filipino guest workers", which they could withhold if the Philippine government angered them.

[2] The first record U.S. authorities had of Khalifa reportedly came in 1992, when his alias "Barra" appeared on a bomb-making manual carried by Ahmed Ajaj who entered the United States on a false passport.

[16] When the FBI looked inside Khalifa's luggage, they found manuals in Arabic on training terrorists, which covered subjects such as bomb-making and other violent activities.

Reports state that around 25 to 30 armed men raided Khalifa's residence in the middle of the night, attacked him with various weapons, and removed his computer and other intelligence materials.
