Marking the second anniversary of the assassination of the British defense attache in Athens by the November 17 group, the families of terrorist victims and people who survived attacks will start a public awareness campaign against terrorism on Saturday. Greece’s only remaining active terrorist group is the left-wing November 17, which has claimed responsibility for 21 assassinations since first appearing in 1975. At a press conference yesterday, bereaved relatives and terrorist targets who have formed an association named Os Edo (No More) said they would distribute the association’s badge, a black palm, and leaflets against terrorism in central Athens on Saturday. Further information will be available on the group’s website (www. osedo. gr). The Os Edo campaign will include the sending of text messages to CosmOTE mobile telephony subscribers, while the association has appealed for donations from banks and public utility corporations. At 11 a. m. on Saturday, a memorial service will be held in St Paul’s Anglican Church for Brig. Stephen Saunders, killed on June 8, 2000.
