Web portal hilafettakip.com, which is thought to be affiliated with ISIS, threatened on Monday that Turkey will pay for the "crimes" it has committed by attacking ISIS militants in Syria. Turkish military aircraft launched their first air strikes against ISIL on late Friday as part of the US-led coalition. A second military operation against ISIL by Turkish F-16 jets came on Saturday. The web portal called President Recep Tayyip Erdoğan an "infidel" and an "accomplice" who supported the US military intervention in Iraq in 2003. The site also claimed that Erdoğan is facilitating "the crusaders," allowing the US expanded access to İncirlik Air Base so it can support the regime of Syrian President Bashar al-Assad and the terrorist Kurdistan Workers' Party (PKK). Kurdish forces that have links with the PKK are fighting ISIS in northern Syria.
