The attack on Europe’s third-busiest airport was the deadliest in a series of suicide bombings this year in Turkey, part of the US-led coalition against Islamic State and struggling to contain spillover from neighbouring Syria’s war.
President Tayyip Erdogan said the attack should serve as a turning point in the global fight against terrorism, which he said had “no regard for faith or values”.
Five Saudis and two Iraqis were among the dead, a Turkish official said. Citizens from China, Jordan, Tunisia, Uzbekistan, Iran and Ukraine were also among the 13 foreigners killed.
One attacker opened fire in the departures hall with an automatic rifle, sending passengers diving for cover and trying to flee, before all three blew themselves up in or around the arrivals hall a floor below, witnesses and officials said.
Video footage showed one of the attackers inside the terminal building being shot, apparently by a police officer, before falling to the ground as people scattered. The attacker then blew himself up around 20 seconds later.
“It’s a jigsaw puzzle ... The authorities are going through CCTV footage, witness statements,” a Turkish official said.
The Dogan news agency said autopsies on the three bombers, whose torsos were ripped apart, had been completed and that they may have been foreign nationals, without citing its sources.
