[WATCH] 41 dead, 239 wounded in Istanbul airport terror attack

13 foreigners among victims of attack on Ataturk International Airport as three terrorists fire at passengers in the terminal and explode two bombs after being shot by police

The death toll in a gun and suicide bomb attack on Istanbul's Ataturk airport has risen to 41, 13 of them foreign nationals, with 239 injured, the Turkish city's governor said.

Three attackers began shooting outside and inside the terminal late on Tuesday and blew themselves up after police fired at them.

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.

Ataturk airport has long been seen as a vulnerable target; there are X-ray scanners at the entrance to the terminal but security checks for cars are limited.

Pictures from the airport terminal showed bodies covered in sheets, with glass and abandoned luggage littering the building.

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”, saying America remained “steadfast in our support for Turkey”.

German Foreign Minister Frank-Walter Steinmeier said: “We grieve for the victims. We stand by Turkey”.

Speaking several hours after the attack, 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 (see video above) 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.

Paul Roos, who was due to fly home to South Africa, told Reuters he saw one of the attackers.

“He was wearing all black. His face was not masked. We ducked behind a counter but I stood up and watched him. Two explosions went off shortly after one another. By that time he had stopped shooting.

“He turned around and started coming towards us. He was holding his gun inside his jacket. He looked around anxiously to see if anyone was going to stop him and then went down the escalator. We heard some more gunfire and then another explosion, and then it was over.”
