Stories shared with Newsweek in recent days by Deniz and others show the group has sunk its tendrils deep into Turkey, a country that may now be in its firing line after being named as part of a Nato alliance to combat the jihadist group. Many fear Isis has the capacity to wreak havoc in a nation that attracts 35 million tourists a year and whose porous border adjoins Isis-controlled territory.
Last week at a Nato summit in Wales, US President Barack Obama said Turkey was part of a core coalition to fight Isis. However, Deniz and other victims of Isis recruitment question their governments willingness or ability to tackle the terrorist organisations infiltration of Turkey. They speak of their frustration at police inaction and of their powerlessness to retrieve their loved ones. In her extended family alone, Deniz says, 15 people including five children have gone to live under Isis rule or fight in its ranks in recent months.
Her story is echoed by others in Istanbul, who describe an organised recruiting network operating online and through religious study groups, targeting young men from Sunni Muslim districts plagued by poverty and drug addiction. One family, whose son joined Isis, says that he was among 19 young men from their neighbourhood alone who left for Syria recently, with at least four others planning to join them soon.
