“I find this totally astonishing,” said Professor Larry Kobilinsky of the John Jay College of Criminal Justice. “I’ve never seen such a massive crime scene looked at for five hours. It’s just impossible. You’re going to compromise, you’re going to contaminate evidence. … They should not have turned this open to the public.”
Passengers walked over shards of glass as workers tried to wash away blood. The stench of smoke still lingered in the air after three gunmen opened fire and detonated explosives at Ataturk Airport, wounding 239 people.
But the airport’s operator defended its actions and its security, saying it exceeds international standards.
And unlike many American and European airports, “We have security checkpoints at the entrance of the terminal building,” TAV Airports CEO Sani Sener said.
Those extra measures didn’t stop the trio of suicide bombers, who started firing high-powered rifles immediately after getting out of a taxi, Sener said.
Despite the horror and carnage, “Everything’s quite calm right now, which is a little surreal as opposed to the scenes we saw here last night,” witness Laurence Cameron said.
“I was in the airport this morning looking for my lost luggage,” he said. “They were sweeping up debris, and someone had hung up a big Turkish flag, pretty much right at the spot where (a) bomb had gone off — sort of an act of defiance, which was quite moving.”
Victims from around the world
Many of the 41 dead were Turkish, including 10 airport staff members, Sener said.
The attack killed six Saudis and wounded 27 more, the Saudi Arabian foreign ministry said.
The other victims included two Iraqis, one Tunisian, one Chinese, one Iranian, one Ukrainian, one Jordanian and one person from Uzbekistan, a Turkish official said. Three of the foreigners had dual Turkish citizenship.
Of the 239 people wounded Tuesday night, 128 remained hospitalized Wednesday, officials said.
While no one has claimed responsibility for the attack, “all information and evidence” points to ISIS, Interior Minister Efkan Ala said. “But nothing is for certain.”
And Prime Minister Binali Yildirim said initial findings “suggest all three attackers first opened fire then detonated themselves.”
And just like the Brussels attack, the terrorists in Istanbul took a taxi to the airport.
The Istanbul taxi driver was interviewed by police and later released, the Turkish state news agency Anadolu reported.
‘Bloody boot marks’
The cacophony of gunfire Tuesday night was quickly followed by the deafening blows of three explosions.
Witness Sue Savage said about 30 people were herded into a women’s prayer room until authorities led them out and down an escalator into the main terminal hall.
“There was a lot of blood,” she said. “There was so much glass on the floor, they were scuffing it aside so we didn’t slip.”
Video from inside the terminal shows the bright orange flash of fire from one of the explosions. Victims stagger. Some fall on the slippery, blood-covered floor.
Another video shows a gunman dropping his weapon when he’s apparently shot by a security officer. The man slumps to the ground, and the officer briefly stands over him before running.
About 10 seconds later, a bomb detonates.
The three terrorists
The assailants have not been identified, but there is a “strong suggestion that they are foreign,” a senior Turkish government source told CNN.
Experts say Turkey is especially vulnerable due to the variety of terrorists operating there.
“You cannot protect these airports 100% … especially in a place like Turkey, where ISIS has cells everywhere,” said retired Lt. Col. Rick Francona, a former U.S. military attaché in Syria.
Even though Ataturk Airport is “one of the most secure airports in the world,” CNN senior law enforcement analyst Tom Fuentes said, the airport has been “very overwhelmed for several decades with terrorism from PKK.”
ISIS promised an uptick in attacks during the holy month of Ramadan, which is nearing its end.
And the terror group has reason to detest Turkey: The country is helping the U.S.-led coalition attack ISIS targets in neighboring Iraq and Syria. Turkey allows coalition planes to fly raids from its territory.
Adding to the instability: Last year, Turkey resumed hostilities with the PKK, Kurdish militant separatists, after a two-year cease fire broke down.
But over the last few months, “the Turks have really changed their focus from only the PKK to going after ISIS as well,” Francona said.
8 attacks so far this year
Turkey has spent much of this year reeling from terror attacks as it weathers bombing campaigns by both ISIS and Kurdish militants.
The attack marked the eighth suicide bombing event in Turkey this year. At least 140 people have been killed.
The violence has also rattled Turkey’s tourism industry, a key sector of the national economy.
Analyst: Retaliation ‘with full war’ possible
If ISIS is responsible for the attack, Turkey likely “will retaliate with full war,” said Soner Cagaptay
of the Turkish Research Program at the Washington Institute.
“I would expect that Turkey’s vengeance will come down like rain from hell,” he said. “For Turkey now, fighting the so-called Islamic State is going to be priority number one.”
President Recep Tayyip Erdogan called for a unified international fight against terrorism following the attack.
“Make no mistake: For terrorist organizations, there is no difference between Istanbul and London, Ankara and Berlin, Izmir and Chicago or Antalya and Rome,” he said.
CIA Director John Brennan warned the United States could certainly be an ISIS target.
“The United States, as we well know, is leading the coalition to try and destroy as much of this poison inside of Syria (and) Iraq as possible,” Brennan said. “So it would be surprising to me that ISIL (is) not trying to hit us both in the region as well as in our homeland.”
