A controversial court case, in which defendants have been barred from speaking Kurdish, reflects deeper tensions as Turkey tries to reconcile with a restive minority.
Turkey's closing of the largest Kurdish party, the Democratic Society Party (DTP), has sparked deadly riots and could stall these reform efforts. Turkey had recently introduced a reform package friendly to its restive Kurdish minority.
Despite its secular roots, a major Kurdish political party is fighting to regain conservative Kurdish votes from the ruling party.
The country's highest court is weighing whether to allow a motion to shut down the party, saying its Islamic initiatives cross a constitutional line.
