A few hours down the road, across the border, Syrian Kurds seized control of their region from Syrian government forces earlier this year. Now children are learning Kurdish as a first language. Kurds in neighboring Iraq have had that right for years.

But Turkish Prime Minister Recep Tayyip Erdogan recently rejected calls for Kurdish education in the mother tongue. He called it a terrorist demand of the Kurdish rebel group PKK.

"He says there is no such thing as education in the mother tongue. He says the country's official language is Turkish, and the government has its duty with Kurdish classes in schools and universities."

Kurdish politicians face increasing pressure if they violate language restrictions.

The latest offenses that Diyarbakir's mayor is accused of include publishing children's books in Kurdish. Thousands of members of his party have been detained this year under anti-terrorism laws.

But the Kurdish language and culture are increasingly making their presence felt. Dorian Jones spoke to Farqin, a local singer.

"He says the demands of Kurds in Iraq and in Syria will push the demands of Kurds in Turkey. He says any freedom struggle there will definitely affect the people in Turkey. He says Turkey is definitely under the shadow of the struggles in those countries and cannot be isolated."
