Mohamed Boudiaf
Arrested and sentenced to death in 1964, he escaped from the El Harrach prison on May 1, 1966. Exiled in Switzerland, he became a doctor of law. After the riots of 1988, the Algerian president Chadli Ben Djedid proposed a new constitution calling for political pluralism. Aït Ahmed was invited to return to his country, where he came back in December 1989, at the head of the FFS, but again left his country after the assassination of the President, Mohamed Boudiaf, in June 1992. He repeatedly returned to Algeria since then, including during the 50th anniversary of the outbreak of the war of liberation (November 1, 1954). Aït Ahmed died at the age of 89 in Lausanne, Switzerland on 23 December 2015.
