Kurdish demonstrators continued to battle Turkish police with rocks and firebombs in Yuksekova on Sunday to protest against a decision by the country's top court to shut down a pro-Kurdish political party on charges of ties to militants.
The party's lawmakers said they would boycott parliament.
The party was banned on Friday, a day after the main Kurdish rebel group claimed responsibility for killing seven Turkish soldiers in an ambush in central Turkey, an attack that outraged the country.
The ban and ensuing violence deepened uncertainty over efforts to end a conflict between the state and its largest ethnic minority.
A crowd pelted armoured police vehicles with stones and firebombs in the town of Yuksekova, close to the borders with Iraq and Iran, Anatolia news video showed.
Police used water canons against protesters who blocked streets with barricades and burned tyres.
The political turmoil has jeopardised a government project to reconcile with minority Kurds in the hopes of ending the fight with Kurdish rebels.
The court said in its ruling that the party had ties to the rebel Kurdistan Workers' Party, or PKK, which has fought for autonomy from the Turkish state since 1984.
The court also barred Turk and legislator Aysel Tugluk from joining any political party for five years along with 35 other party members, including
Leyla Zana, a prominent Kurd who served a decade in prison on charges of separatism.
The court has shut down several Kurdish party on similar charges in the past.
The predecessor of the Democratic Society Party had dissolved itself in 2005.
The party is the 27th to be shut down in Turkey since 1968.
