Athens, Greece - The anarchist group Red and Black, disavowed any involvement in the December killing of a police officer guarding a British diplomat’s house. Red and Black has carried out a number of arson, and other attacks against corporate and state targets but say they "are not murderers, bombers or terrorists.” The leftist November 17 group has also been considered a suspect. They are responsible for numerous bombings, and 23 killings, including a similar murder of British military attache Brigadier Stephen Saunders, in June 2000.
