Turkish PM Ahmet Davutoglu denied Wednesday that leaders of Islamic State and Sham ISIS were crossing Turkish borders to fight in Syria and Iraq, responding to an article published by American magazine Newsweek. Turkish PM also said that Turkey was ready for any security or intelligence cooperation in this regard, in a statement to Sky News Arabic. He added that his country will defend itself against any unfair accusations. Ex-ISIS fighter Chirco Omar had declared to Newsweek that Turkish authorities allowed combatants to travel through its territory, and that ISIS "terrorists" were fluent in Turkish.
