Huseynov, editor-in-chief of the "Monitor" news magazine, was slain in Baku on 2 March 2005.
Relatives and rights groups blame the government for the killing. President Aliyev has called the journalist's assassination "a provocation against the state."
Officials say Huseynov was shot dead by two Georgian Azeris who fled the country after the killing. In Georgia, authorities say the suspects are not in the country.
