Nasser al-Bahri (1972 – December 26, 2015), also known by his kunya or nom de guerre as Abu Jandal – "father of death",[1][2] was a member of al-Qaeda in Afghanistan from 1996 to 2000. He gave his bayat (secret oath of allegiance) to Osama bin Laden in 1998, an experience he describes in detail in his memoir.[3] He was in al-Qaeda for four years, first as one of bin Laden's twelve bodyguards,[4] and then as head of Osama bin Laden's security detail.[5] A citizen of Yemen born in Saudi Arabia, Al-Bahri was radicalized in his teens by dissident Saudi Ulemas and participated in clandestine political activities which were funded in part by people trafficking.[6] Having determined to become a jihadist he went first to Bosnia[7] and then, briefly, to Somalia before arriving in Afghanistan in 1996 in the hope of joining Al-Qaeda, which he soon did. After four years, al-Bahri became "disillusioned", largely because bin Laden consolidated al-Qaeda's relationship with the Taliban by giving his bayat to its leader, Mullah Omar,[8] but also because he had married and become a father.
