"FIRING AT ANYONE"

Paul Roos, 77, described seeing one of the attackers "randomly shooting" in the departures hall.

"He was just firing at anyone coming in front of him. He was wearing all black. His face was not masked. I was 50 meters (55 yards) away from him," said Roos, a South African returning to Cape Town with his wife after a holiday in southern Turkey.

"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," Roos told Reuters.

"He turned around and started coming toward 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."

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

"The attack, which took place during the holy month of Ramadan, shows that terrorism strikes with no regard for faith and values," he said in a statement.

"The bombs that exploded in Istanbul today could have gone off at any airport in any city around the world," he said, urging all governments to join forces against terrorism.

The United States said it stood in solidarity with Turkey, its NATO ally, and that such attacks would only reinforce their joint determination. United Nations Secretary-General Ban Ki-moon stressed the need to intensify global efforts to combat extremism.
