TURKEY-SYRIA-UNREST-PROTEST

A protester walks by the Cemevi square (an holy place for Turkish Alevites) during clashes with Turkish riot police in Istanbul's Gazi district, on July 26, 2015. A Turkish policeman was killed on July 26, 2015 during clashes with protesters in the flashpoint Istanbul district of Gazi which have raged for the last three days following the death of a leftist activist during raids by the security forces. 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.
