The Kurdish-Turkish peace process saw negotiations begin between jailed Kurdistan Workers' Party (PKK) leader Abdullah Ocalan and the Turkish government in late 2012. A ceasefire was called, and the PKK agreed to withdraw from Turkish Kurdistan into Iraqi Kurdistan. In 2014, anger increased among Turkish Kurds with what they saw as the Turkish state's facilitation of the Islamic State of Iraq and the Levant's assault on Syrian Kurds during the Rojava–Islamist conflict, culminating in the 2014 Kurdish riots in Turkey during the Siege of Kobanî. The June 2015 Turkish general election saw Turkey's ruling Justice and Development Party (AKP) lose its majority, and gains for the Peoples' Democratic Party (HDP). Tensions increased further after the Suruç bombing and Ceylanpınar incident in July, after which the Turkish government launched the 2015 police raids in Turkey and attacked PKK positions in Iraq, prompting the PKK to call off its ceasefire.
