This was possibly the first planned attack by ISIL on Turkish soil , although previous incidents such as the 2013 Reyhanlı bombings , the 2015 Istanbul suicide bombing , and the 2015 Diyarbakır rally bombings have also been blamed by some on ISIL . The bombing resulted in a new escalation between Turkey and ISIL , with Turkish soldiers and ISIL militants directly engaging in the border town of Kilis on 24 July 2015 . This led to Turkey launching Operation Martyr Yalçın , a series of airstrikes against mostly Kurdish militant positions in Northern Iraq and Syria . Large-scale operations against PKK , but including some ISIL targets , began on 24 July ; however , most arrests were of PKK members . The bombing was met with international condemnation by a variety of organizations , as well as promises by the governing Justice and Development Party ( AKP ) to tighten the Turkish-Syrian border following the attack . The opposition criticised the government for not securing the border beforehand , while the Peoples ' Democratic Party ( HDP ) also came under scrutiny for endorsing the crossing of the victims past the border despite significant threats from ISIL
