After the defeat of the invading Soviets in Afghanistan, there was a power struggle between Osama bin Laden and al Qaeda co-founder Sheik Abdullah Azzam as to how to use the funds they raised, as well as the mujahadeen. “On November 24, 1989, Azzam and his two sons were killed by a car bomb in Peshawar [Pakistan] as they drove to juma (Friday prayers). The murders remain unsolved, and although he expressed public grief at their deaths, some U.S. intelligence officials believe that Osama bin Laden himself gave the order for the hit.”
