Another Terrorist Attack - Istanbul's Largest Airport

Blasts rock Istanbul’s largest airport

Multiple casualties have been reported after at least two explosions rocked Istanbul’s Ataturk Airport on Tuesday evening."It was just a massive crowd of screaming people. Some were falling over themselves. A poor chap in a wheelchair was just left, and everyone just rushed to the back of the building, and then people ran the other way and no one really seemed to know what was going on," he said. "Where you normally hail a taxi, that is where the attack happened. The ground is just kind of shredded. There is bloodstains on the floor as well."

One of the attackers "randomly opened fire" in the terminal building before the explosions, a witness told Reuters. There were two explosions, followed by more shooting, then a third explosion.

An AK-47 was seen on the floor of the airport after the attack.

• Americans in Turkey were warned of increased terror threats throughout the country on Monday.

  “Foreign and US tourists have been explicitly targeted by international and indigenous terrorist organizations,” the US State Department said in a statement a day before the terror attack at Ataturk.

  US citizens were encouraged to avoid travel to southeastern Turkey, especially near the Syrian border; Istanbul was not specifically mentioned in the warning.

The Port Authority of New York and New Jersey has stepped up security in the New York City area in the wake of the terror attack in Turkey, the local ABC affiliate added.
