Rifai Ahmed Taha Musa, one of Egypt’s most notorious al Qaeda-linked terrorists, attended the U.S. embassy protest in Cairo on September 11. Musa was just one of several al Qaeda-affiliated jihadists who was present at the rally, imploring followers to punish those who produced the anti-Islam film Innocence of Muslims.

Musa’s al Qaeda ties were publicly recognized by the U.S. government as early as 1998. He was included as a signatory on al Qaeda’s infamous February 1998 fatwa justifying terrorist attacks against American civilians. Musa would later disavow any involvement in the fatwa, but his al Qaeda ties are well established.
