ISTANBUL - Turkish Prime Minister Binali Yildirim on Wednesday blamed the Islamic State (IS) for the terrorist attacks on Istanbul's Ataturk Airport that killed 36 people and injured many others.

There are signs indicating that Tuesday night's attacks were carried out by the IS, but efforts to identify the attackers are still under way, Yildirim told reporters at the airport.

Three suicide bombers had arrived at the airport by taxi and opened fire before blowing themselves up, said the prime minister. Foreign nationals were among the dead, he said.
