Baku, Azerbaijan, June 29
Police sources cited in Turkish media say they believe the attackers were affiliated with the Islamic State of Iraq and the Levant (Isil), Telegraph reported.
The methods behind the attack and the fact that tourists may have been targeted led to initial speculation that Isil was involved, and the initial investigation apparently bears that out, though nothing is confirmed at this time.
At least 28 people were killed and another 60 wounded in two explosions at the main airport in Istanbul, Hurriyet reports.
Three suspects blew themselves up at Istanbul Ataturk Airport after police fired on them, government officials said.
