Yesterday in the evening, approximately when the Turkish Prime Minister visited slain Armenian-Turkish bilingual weekly editor-in-chief Hrant Dink's family, the 'Agos' editorial office received a letter from an earlier unknown ultra-nationalistic organization "Squadron of Avengers", RFE RL reports. Particularly, the letter says, "After killing of a priest in Trabzon one more enemy of Turkey died and next time the whole 'Agos' editorial office will blast in order all the enemies would die." The unknown author of the letter underlines that these warnings concern those who will dare express their dreams aloud. "If you call the events of 1915 a 'genocide', it means that you have not seen real genocide. Genocide starts now," says the letter. After receiving the letter 'Agos' staff immediately turned to the police. Currently the editorial office is surrounded by law enforcement bodies. The building has undergone a thorough search, but no explosive device was found. But security services continue to keep the district, where 'Agos' office is situated, under strong control.
