Thousands of people have gathered in Istanbul to pay tribute to ethnic Armenian journalist Hrant Dink and to protest a court ruling that his murder was not planned as part of a wider conspiracy.
Television reports said around 20,000 people joined the demonstration in Istanbul on Thursday to commemorate the fifth anniversary of his death.
A leading member of Turkey's tiny Armenian community, Dink, 52, was shot dead in broad daylight on January 19, 2007, outside the offices of his bilingual weekly newspaper Agos.
Dink had campaigned for reconciliation between Turks and Armenians and his assassination sent shockwaves through Turkey, growing into a wider scandal following reports that state security forces had known of a plot to kill him but failed to act.
"Murderer state will account for this," and "Shoulder to shoulder against fascism," chanted the crowd near the central Taksim Square before marching to the offices of Dink's newspaper.
The crowd, including Dink's widow Rakel and his children, carried two large black banners declaring "We will not forget" and "We will not forgive."
Many demonstrators also carried placards saying "We are all Hrant Dink, we are all Armenians," in Turkish and Armenian.
Dink's self-confessed murderer Ogun Samast, who shot the journalist in the back of the head, was a jobless high-school dropout and 17 years old at the time. He was sentenced to nearly 23 years in jail in July.
On Tuesday an Istanbul court sentenced Yasin Hayal, 31, to life in prison for inciting the murder.
‘Test for Turkey’
But the court acquitted more than a dozen other suspects, ruling that there was no wider plot to kill Dink -- who had angered nationalists with his views on Turkish-Armenian history -- as alleged by his supporters.
"This (verdict) is a scandal. This is why this commemoration turned out to be so strong," said Ufuk Uras, a Kurdish member of Turkey's parliament.
Among those acquitted was alleged ringleader Erhan Tuncel, who was freed after spending five years in jail.
"They surrounded us with lies. It has been like this for five years and they finally gave us two people and asked us to be content with them," journalist Karin Karakasli told the crowd.
Dink's family is seeking a deeper investigation to uncover state officials who were allegedly involved the murder.
Demonstrators on Thursday left red carnations and lit candles at the spot where Dink was shot, while the words "Hrant Dink was murdered here" were written on the pavement.
President Abdullah Gul described the trial as a test for Turkey.
"It is an important test for us that this trial process should be concluded in the most transparent way and in harmony with our laws," Gul told the media.
Prime Minister Recep Tayyip Erdogan said the government did its best to help solve the murder.
"I see that public consciousness is not satisfied," he said in a TV interview broadcast Wednesday. "There have been various expectations (about the case). It is possible to share some of them but I cannot join them in general."
The chief judge in the case, Rustem Eryilmaz, also expressed doubts about his own verdict, saying that any "connections" between the culprits and the state could not be clearly established before the trial.
"However, this is the only decision we could take, according to the available evidence," Eryilmaz told private news channel NTV.
