State and renewed tensions in Turkey The PKK engaged the Islamic State of Iraq and the Levant (ISIL) forces in Syria in mid-July 2014 as part of the Syrian Civil War. In August the PKK engaged IS in Northern Iraq and pressured the Government of Turkey to take a stand against IS. PKK forces helped tens of thousands of Yazidis escape an encircled Mount Sinjar. In September 2014, during the Siege of Kobanî, some PKK fighters engaged with Islamic State forces in Syria who were attacking Kurdish city Kobane, which resulted in conflicts with Turks on the border and an end to a cease-fire that had been in place over a year. The PKK said Turkey was supporting ISIS. The PKK participated in many offensives against ISIS in Iraq and Syria. A number of Turkish Kurds rallied in large-scale street protests, demanding that the government in Ankara take more forceful action to combat IS and to enable Kurdish militants already engaged against IS to more freely move and resupply. These protests included a PKK call for its supporters to turn out. Clashes between police and protesters killed at least 31 people. The Turkish government continued to restrict PKK-associated fighters' movement across its borders, arresting 260 People's Protection Units fighters who were moving back into Turkey. On 14 October, Turkish Air Force fighter-bombers attacked PKK positions in the vicinity of Daglica, Hakkari Province. Turkish military statements stated that the bombings were in response to PKK attacks on a Turkish military outpost in the area. The Firat news agency, which Al Jazeera describes as "close to the PKK", stated that Turkish forces had been shelling the PKK positions for days beforehand and that the PKK action had itself been retaliation for those artillery strikes. The PKK had already reported several Turkish attacks against their troops months before Turkish bombing started. July 2015–present: Third insurgency In the months before the parliamentary election of 2015, as the "Kurdish-focused" HDP's likelihood of crossing the 10% threshold for entry into the government seemed more likely, Erdogan gave speeches and made comments that repudiated the settlement process and the existence of a Kurdish problem and refusing to recognize the HDP as having any role to play despite their long participation as intermediaries. These announcements increased distrust of the government's good faith among Kurdish leaders. In July 2015, Turkey finally became involved in the war against ISIL. While
