A prominent pro-Kurdish lawyer and human rights activist has been killed by shooting in Turkey’s south-eastern city of Diyarbakir.
Police in Istanbul fired water cannon to disperse crowds demonstrating against Mr Elci’s death.
Tahir Elci was killed in a gun battle between police and unidentified gunmen.
He had been making a statement calling for an end to violence between the Turkish state and the Kurdish rebel group the PKK when he was shot dead.
A policeman also died in Saturday’s clash. A curfew has now been imposed in the neighbourhood where Mr Elci was shot.
