On October 10, 2015, Turkey was hit again in Ankara by the deadliest attack in its history: 102 dead, over 500 injured. It has been the third attack since June perpetrated by young jihadists from Adıyaman, a city of 200,000 inhabitants in southeastern Turkey. A group of 21 potential human bombs is now wanted by the police. The families of four of these young people claim they have warned the authorities for months in order to denounce their own children. In vain. How could this terrorist group establish itself and recruit youngsters in Turkey? How could the members come and go to Syria without being detected by the Turkish security services? The Turkish authorities are at best accused of inaction, at worst of complicity. President Erdogan has taken advantage of the attacks to justify the repression of Kurds in the south. As a result of the conflict, 250 civilians have been killed in three months. Would it be a strategy of chaos to win back, in the frame of the parliamentary elections of November 1, the absolute majority lost in June? But at what cost?
