Speaking several hours after Tuesday's attack, Mr Yildirim said at least 36 people were killed and many wounded, some seriously, with foreigners likely to be among the victims.He said the attackers had arrived at the airport in a taxi. Footage on social media shows one of the attackers running in the departure hall as people around him flee. He is shot by police and remains on the ground for about 20 seconds before blowing himself up.
All three attackers were killed. Justice Minister Bekir Bozdag put the number of injured at 147. Taxis were used to rush casualties to hospital after the attack. Desperate relatives of those missing later gathered outside a local hospital where many victims were taken. Some expressed anger about the lack of information.
Flights in and out of the airport were suspended after the attack. The US Federal Aviation Administration initially grounded all services between the US and Istanbul but the stoppage was later lifted.
Flights have now resumed at the airport, but information boards showed about one-third had been cancelled, with many delays.
