Photos Believed to Be of 3 Istanbul Attackers Emerge

Images have emerged that are believed to be of the three men who are suspected of launching an attack on Istanbul's Ataturk Airport, killing 44 people and injuring more than 200 others.

One image shows three men as they walk into the airport Tuesday night, with one carrying what appears to be a duffel bag. The other two men are seen wearing baseball caps.

Another photo shows a man dressed in all black, circled in red, walking through the airport. A board with the flight arrival and departure information is seen to the left of the frame. The man holds an item with both of his hands, but it is unclear from the image what it is. The photo has a time stamp of 9:54 p.m. local time.

The third picture shows a man, circled in red, standing at what appears to be the airport's entrance. Painted lines, likely for a crosswalk, appear at the top of the frame. The man appears to be wearing a puffy black jacket, blue jeans and sneakers. He faces in a diagonal direction, as two other people, one outside and another walking in, appear in the image with him.

The man seen next to the alleged attacker carries a rolling luggage and appears to be a pilot from his uniform.

The images, grabbed from a CCTV video, were made available by the Turkish Haberturk newspaper Thursday.

On Thursday, the death toll from the terrorist attack climbed to 44 after a 25-year-old victim died in the hospital, according to Turkish authorities. The three attackers were from Russia, Kyrgyzstan and Uzbekistan, the Turkish prime minister's office confirmed with ABC News.

The three men shared a home in Istanbul for the past month, Turkish officials said. During the several weeks, they lived in an apartment with a reinforced steel door, according to neighbors.

Turkey's interior minister said about the attack, "all findings show it's ISIS," while CIA Director John Brennan said Tuesday that the attack "bears the hallmarks" of the terrorist group's "depravity."

Turkish officials said the attackers opened fire with guns at a security checkpoint before blowing themselves up.
