Diyarbakir

Local reports said thousands of people gathered to watch the statement on big screens in the cities of Diyarbakir and Van in the predominantly Kurdish south-east.

In March, six people were arrested for clashes involving fireworks before and after a match between Bursa's Bursaspor and Diyarbakir's Amedspor.

In the southeastern city of Diyarbakir, 46-year-old business owner Mikail Bakan said: "All the Muslim world needs to be one against Israel."

The other at-risk sites under consideration are the Saint Sophia Cathedral in Ukraine’s capital, Kyiv; the historic center of Lviv, in western Ukraine; the ancient city of Nessebar in Bulgaria; the Diyarbakir Fortress in Turkey; and the Kamchatka Volcanoes in Russia’s far east.

Ardelan Mese, a 26-year-old café owner in Diyarbakir, the country's largest Kurdish-majority city, called Sunday's election "a matter of life and death now."
