The Suruç bombing was a suicide attack by the Islamic State of Iraq and the Levant (ISIL) against Turkish leftists that took place in the Suruç district of Şanlıurfa Province in Turkey on 20 July 2015, outside the Amara Culture Centre. A total of 34 people were killed (including the perpetrator) and 104 were reported injured. Most victims were members of the Socialist Party of the Oppressed (ESP) Youth Wing and the Socialist Youth Associations Federation (SGDF), university students who were giving a press statement on their planned trip to reconstruct the Syrian border town of Kobanî.Kobanî, which is approximately 10 km from Suruç, had been under siege by Islamic State forces until January 2015. More than 300 members of the SGDF had travelled from İstanbul to Suruç to participate in three to four days of rebuilding work in Kobanî, and had been staying at the Amara Cultural Centre while preparing to cross the border. The explosion was caught on camera.The Islamic State claimed responsibility for the attack the following day. ISIL had allegedly made the decision to pursue more active operations in Turkey just days before the attack. The attacker, Şeyh Abdurrahman Alagöz (20), a Kurd from Adıyaman, reportedly had links to Islamic State militants. Both the Turkish government and police were accused of turning a blind eye to ISIL activities as part of their collaboration with ISIL and failing to give leftist and Kurdish gatherings the proper law enforcement protection given to other gatherings. Two Turkish police officers were subsequently prosecuted over the bombing. It was possibly the first planned attack by ISIL in Turkey, 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.

Soon after, the Turkish government launched Operation Martyr Yalçın, a series of airstrikes against mostly Kurdish militant positions in Northern Iraq and Syria. Large-scale operations against the Kurdistan Workers Party (PKK), but including some ISIL targets, began on 24 July; however, most arrests were of PKK members. This led to the resumption of the Kurdish-Turkish conflict (2015-present).

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 Syria-Turkey border following the attack. The opposition criticised the government for not securing the border beforehand, while the Peoples' Democratic Party (HDP) was also criticised for endorsing the intended crossing of the victims to Syria despite the Kobanî massacre.
