“On November 24, 1989, [Palestinian cleric and mentor of Osama bin Laden, Abdullah] Azzam rode to the mosque [in Peshawar, Pakistan] with his sons, Ibrahim and Mohammed, who was the driver. As Mohammed was parking, a roadside bomb made from twenty kilograms of TNT exploded with such force that the car shattered. …Earlier that Friday, on the streets of Peshawar, Azzam’s main rival, [Egyptian jihadist] Ayman al-Zawahiri, had been spreading rumors that Azzam had been working for the Americans.”
