Three suspects detained in Turkey for Armenian famous journalist Hrant Dink's murder. Istanbul governor Muammer Güler informed that investigators have irrefutable proofs and soon the crime will be revealed. On Friday the 53-year-old journalist was shot dead near the editorial office of his 'Agos' newspaper in Istanbul. A couple of hours after Dink's murder several thousand demonstrators gathered in Istanbul to express their anger over the murder. Dink's friends and colleagues say that the motive of crime is political. Dink repeatedly has been put on trial for articles on the Armenian Genocide in Ottoman Empire during World War 1. Turkish nationalists have threatened him several times. Spiritual leader of Turkish Armenians Archbishop Mesrob Mutafyan has declared a 15-day mourning on Hrant Dink's murder, RFE RL reports.
