Family members of the Turkish gunman who shot dead Russian ambassador Andrei Karlov have been released from police questioning.
A number of relatives of Mevlut Mert Altintas were taken into custody earlier this week as police attempted to establish the background to the shooting.
Karlov, the ambassador to Turkey, was shot in the back by Altintas, himself a member of security, as the Russian was giving a speech on Monday.
The body of the Russian ambassador who was assassinated by a Turkish policeman was flown home today.
Andrei Karlov, who was gunned down in an art gallery on Monday, was carried across Esenboga airport's tarmac in a coffin draped in the Russian flag.
A ceremony attended by Ankara's top diplomats and Turkey's Deputy Prime Minister Tugrul Turkes was held before his departure.
Karlov's wife Marina stood in the front row, holding two red carnations. She wept as her husband's coffin was carried by a Turkish guard of honour.
"It was like a movie", says Burhan Ozbilici, who captured the moment Mevlut Mert Altintas shot and killed Andrey Karlov.
Andrey Karlov has been killed in a gun attack at a photo exhibition in the Turkish capital Ankara.
