Two Russian nationals have been identified as suspected Islamic State suicide bombers in the attack that is thought to have been masterminded by a Chechen, Turkish media said on Friday.

"The latest findings point to the Daesh (Islamic State) terrorist organisation," Erdogan told Reuters at the Istanbul Ataturk airport, where he visited the attack site.
