AA12 - Ankara, Ankara, TURKEY : Turkish police use water cannon to disperse demonstrators during a protest condemning a suicide bombing, that killed 32 activists on July 20 in the Turkish border town of Suruc, on July 25, 2015 in Ankara. Turkey's military on July 25 carried out a new wave of air and artillery strikes against Islamic State (IS) jihadists in Syria and Kurdish militants in northern Iraq, in an escalating campaign Ankara says is aimed at rooting out terror. The two-pronged operation against IS and the outlawed Kurdistan Workers Party (PKK) -- two groups who are themselves bitterly opposed -- came after a week of deadly violence in Turkey the authorities blamed on both organisations. Violence in Turkey erupted after the killing of 32 people in a suicide bombing on July 20 in the Turkish town of Suruc on the Syrian border carried out by a 20-year old Turkish man linked to IS.
