Turkish police have used pepper spray and water cannons to disperse a demonstration in Ankara calling for justice over the murder of Turkish-Armenian journalist Hrant Dink, who was shot dead outside his offices eight years ago.
Thousands of people had marched though central Istanbul earlier on January 19 in a peaceful demonstration to remember the killing that sent shock waves around the country.
Dink, 52, was shot dead on January 19, 2007.
Seventeen-year-old Ogun Samast confessed to the murder and was sentenced to almost 23 years in jail in 2011.
But the murder grew into a wider scandal after it emerged that the security forces knew of a plot to kill Dink, but failed to act.
Dink had long pushed for a reconciliation between Turks and Armenians.
Armenians accuse Ottoman forces during World War I of carrying out a genocide against their forebears that left an estimated 1.5 million people dead.
Turkey has vehemently resisted terming the mass killings as genocide.
