Turkey's state-run news agency says authorities have released the family members of the policeman who killed the Russian ambassador.
The policeman's parents, sister and three other relatives were among 11 people detained over the killing of Ambassador Andrei Karlov as he delivered a speech at the opening of a photo exhibition in Ankara. The policeman, Mevlut Mert Altintas, was later killed in a police operation.
The Anadolu Agency says the six family members were released Thursday without charges. Those still in custody include Altintas' roommate.
A ceremony for Karlov, to be attended by President Vladimir Putin, was being held in Moscow.
