Abbas was running a military camp in Aknoul and was assassinated in Fes in June 1956 allegedly by Karim Hajjaj, a member of the Istiqlal party. His assassination was allegedly ordered by Mehdi Ben Barka. Karim Hajjaj was arrested and convicted of his murder but was later pardoned by the king Mohammed V.
