Protesters threw stones and set off firecrackers in response to police firing teargas in the southeastern city of Cizre on Saturday.
Skirmishes were also reported in Diyarbakir, the largest city in southeastern Anatolia. At least 20 Kurdish protestors were arrested.
On Friday, PKK militants killed one Turkish soldier and injured six others in an attack on a military checkpoint in Diyarbakir.
Clashes between Turkish troops and PKK fighters have intensified in recent months.
Earlier this week, eight PKK militants and one police officer were killed in clashes in the southeastern province of Sirnak, which borders Syria and Iraq.
The PKK has been fighting for an autonomous Kurdish region in Turkey since the 1980s. The conflict has left tens of thousands dead.
