Turkey–ISIL conflict  The Turkey–ISIL conflict is an ongoing series of attacks and clashes between Turkey and the self-proclaimed Islamic State of Iraq and the Levant (ISIL) as part of the spillover of the Syrian Civil War. Turkey claims to have been the first country which designated ISIL as a terrorist organization. ISIL is suspected of involvement in or responsibility for the terrorist attacks on Turkish soil in May 2013 in Reyhanlı and March 2014 on Turkish police, the 5 June 2015 Diyarbakır rally bombing and most notably the 20 July 2015 Suruç bombing killing 33 young Kurdish activists which ignited the Third Phase of the Kurdish–Turkish conflict ongoing since 1978 and reignited fighting amongst Turkish security forces and the PKK. The Turkish government until July 2015 had attacked ISIL once militarily, in January 2014. In September 2014, Turkey joined a US-led coalition 'to fight ISIL'. On 23 July 2015, Turkey allowed the United States Air Force to use İncirlik and Diyarbakır air bases in southern Turkey for their airstrikes on ISIL. Also on 23 July, after an alleged ISIL attack on a Turkish border outpost in Kilis Province killing one Turkish soldier, the Turkish army with tanks shelled ISIL militants in Syria killing one militant and destroying several ISIL vehicles. On 24 July 2015, an anonymous report appeared on a Turkish newspaper/website stating that the United States had agreed with Turkey on a 'partial no-fly zone' in northern Syria. While no official statement about the zone has been released, commentators still speculate about the real motives and objectives of Turkey and the US with the supposed 'buffer zone' or 'ISIL-free zone'. On 24 and 25 July, Turkey carried out three waves of airstrikes on ISIL in Syria hitting a number of ISIL targets and killing 35 ISIL militants. After these events, ISIL publications had upped the rhetoric against the Turkish government, condemning it as one of many "apostate regimes" allying with the "crusaders". In the Turkish-language ISIL digital monthly "Konstantiniyye", an article promised the "conquest of Istanbul". In the meantime the Turkish authorities have arrested around 1,200 people inside Turkey through the past year for suspected links with ISIL. This means that Turkey is at active war with ISIL. On January 12, 2016, an ISIL suicide bomber committed the 2016 Istanbul bombing in Istanbul's historic Sultanahmet Square, killing 12 people. In response to the bombing, the Turkish Army commenced tank and artillery strikes on ISIL positions in Syria and Iraq killing nearly 200 ISIL fighters.
