Kamel Daoudi was born on 3 August 1974 in Algeria, but the family moved to France in 1979 for a better life. Daoudi was a good student in school in the capital of Paris, but the income reductions faced by his family in the 1990s and their moving to a lower-class area led to Daoudi having a bitter view of the French government. He joined Djamel Beghal's Takfir wal-Hijra group, a matrix of terrorist cells more extreme than Osama bin Laden himself, and he became a computer expert. In 2000-2001, he was trained at al-Qaeda training camps in Afghanistan, and he was qualified in handling explosives. He prepared the bombs to be used in Nizar Trabelsi's suicide bombing at the United States embassy in Paris, France, but he was arrested on 29 September 2001 in London, United Kingdom. On 15 March 2005, he was sentenced to nine years in jail in France.
