Scores of demonstrators clashed with police in southeast Turkey ahead of a rally organised by a pro-Kurdish political party.
Police in the city of Diyarbakir used water cannons and teargas against Kurdish protesters.
The rally was partly organised in protest to call for the release of the jailed Kurdish militant Abdullah Ocalan.
The demonstration coincided with the first anniversary of a declaration of ‘democratic autonomy’ by Kurdish politicians. It was also exactly one year after Kurdistan Workers Party (PKK) guerrillas killed 13 soldiers in an attack in Diyarbakir.
Meanwhile militants elsewhere in the region detonated a bomb which wounded 12 police officers.
