"When I was making my statements, I did not know that a youth had been killed. If I had known, I could have offered my condolences before my speech. It is an unfortunate development which has drawn me into an incident which has nothing to do with sports. I am against any kind of terrorism in sports and I condemn the Serbian consul general's remarks about me." Ataman was referring to the Serbian consul general calling him a terrorist. "The incident has reached political dimensions. Meanwhile, the Serbian President pointed at me as a target by saying 'Ergin Ataman will not enter Serbia anymore,' I request that this statement be reversed as soon as possible," he continued.Zoran Markovic, Serbia's consul general in Istanbul, said that Ataman's statements a during press conference were unacceptable. Emphasizing that eye witnesses confirmed the incident, the Serbian consul general continued by saying, "Turkish police forces and the Galatasaray board were informed and we [the Serbian consulate] were all prepared for any scenario."
