One of Turkey's best-known writers, Yasar Kemal, 92, has died in an Istanbul hospital following respiratory and organ failure.

Medics said his health deteriorated rapidly over the past week.
Mr Kemal - an ethnic Kurd born in south-eastern Turkey - won international fame for his first novel, Memed, My Hawk, published in 1955.
It became a worldwide success and was published in 40 languages.
Nine of his novels were made into films, and he is credited for re-establishing Turkish as a literary language.
Turkish Prime Minister Ahmet Davutoglu said in a statement he was feeling "sorrow... at the loss of the great writer and artist".
The prime minister singled out Kemal's ability to "maintain his dissident attitude and express the truth without holding back at times when speaking the truth was hard".
