Protesters try to protect themselves as Turkish anti-riot police fire water cannons to disperse a demonstration in Istanbul's Gazi district, on July 26, 2015. Tensions across the country are high, with police routinely using water cannon to disperse nightly protests in Istanbul and other cities denouncing IS and the government's policies on Syria. Turkey has launched a two-pronged "anti-terror" cross-border offensive against Islamic State (IS) jihadists and Kurdistan Workers Party (PKK) militants after a wave of violence in the country, pounding their positions with air strikes and artillery. But the expansion of the campaign to include not just IS targets in Syria but PKK rebels in neighbouring northern Iraq -- themselves bitterly opposed to the jihadists -- has put in jeopardy a truce with the Kurdish militants that has largely held since 2013.
