In 1993, Black transferred from London to Khartoum, Sudan, where he served as CIA Station Chief until 1995. This was at a low point in U.S.-Sudanese relations, particularly over the latter country's sponsorship of terror and the harboring of Al Qaeda founder Osama bin Laden. Black oversaw the collection of human intelligence on terrorist cells and support structures, and toward the end of his tenure, he was targeted by Al Qaeda for assassination {see Woodward, "Bush At War", p. 9}. Black was also responsible for the collection of intelligence that directly led to the 1994 capture of the terrorist known as Carlos the Jackal.
