Armed clashes persisted on Sunday across Turkey's southeast, where an operation by Turkish forces intensified on the sixth day of a campaign that security sources said had resulted in the death of 110 Kurdish militants.Protests erupted in Istanbul and Diyarbakir, the biggest city in the country's southeast, with hundreds demonstrating against the military operations. Police fired tear gas and rubber bullets to disperse the crowds.

Nusaybin and Dargecit in the border province of Mardin and the historical Sur district of Diyarbakir have also seen fierce battles.
Although rooted in the countryside, militants of the Kurdistan Workers' Party (PKK) have shifted focus in recent years to towns and cities in the southeast, digging trenches and setting up barricades in streets to keep security forces away.Security sources and residents said around 300 houses in Cizre had been damaged by the clashes and undetonated mortar shells lay inside buildings.Electricity was cut in many neighborhoods in Silopi as power transformers were damaged. Food and drinking water were running scarce, residents said.
A two-year ceasefire between Turkey and the PKK fell apart in July, shattering peace talks and reviving a conflict that has ravaged the mainly Kurdish southeast for three decades."We will not get tired," Prime Minister Ahmet Davutoglu said in a speech to his ruling party's supporters. "We will fight day and night until all mountains, cities, districts and neighborhoods of this country are cleansed of terror centers."
