Three attackers opened fire near an entry point to the terminal and blew themselves up after police fired at them, officials say.

Prime Minister Binali Yildirim said early signs suggested the so-called Islamic State was behind the attack.

Recent bombings have been linked to either IS or Kurdish separatists.

There are X-ray scanners at the entrance to the terminal but security checks for cars are limited.

Turkish President Recep Tayyip Erdogan said the attack should serve as a turning point in the global fight against militant groups.

"The bombs that exploded in Istanbul today could have gone off at any airport in any city around the world," he said.

The US called the attack "heinous", and said saying America remained "steadfast in our support for Turkey".
