The arrests of nine senior HDP members – including the party’s two charismatic co-chairs, Selahattin Demirtas and Figen Yuksekdag – marks a new, more confrontational phase in Turkey’s Kurdish conflict. Four hours after the arrests, a car bomb was detonated near the Diyarbakir police headquarters, where four of the MPs were being held. Identifying the perpetrators of the attack has proven difficult, underscoring how deeply convoluted the conflict is. The Kurdistan Freedom Falcons (TAK), a splinter organization of the PKK, claimed responsibility for the attack, but the Islamic State of Iraq and the Levant (ISIL) did as well. The Turkish government has blamed the PKK, claiming that the TAK is its wing that it uses to mount mass-casualty attacks and then deny any connection between the two groups.
