A new chilling photo has surfaced showing what is said to be the three Istanbul airport suicide bombers.
The three were from Russia, Uzbekistan and Kyrgyzstan.
Airport cops were immediately suspicious because the trio wore winter jackets and temperatures were in the 80s.
Each member of the trio wore a suicide vest and carried an AK-47 before killing 42 people and injuring 240 in Tuesday night’s attack inside the country’s largest airport, Ataturk.
In the photo, the suspects are seen walking calmly and smiling as they entered the airport before splitting up.
It is believed that the suspects had trained with ISIS and are part of a cell. However, the terrorist group has not claimed responsibility. Turkey, a bridge between the Middle East and Europe, has been threatened by ISIS in the past.
According to reports, the trio was part of a cell that entered the country last month.
The recent attack in Istanbul was the fourth in the country this year.
Turkish Prime Minister Binali Yildirim told reporters Tuesday: “It became clear with this incident again that terrorism is a global threat. This attack, targeting innocent people is a vile, planned terrorist act.”
Following the attacks in Turkey, a U.S. aircraft blasting a fleet of ISIS vehicles as they flee the newly liberated city of Fallujah, Iraq, where an estimated 250 terrorists were reported killed.
With the July 4 holiday rush about to start, many are wondering if airport security in American needs to be beefed up.
Security expert Nick Casal says U.S. airports may have to adopt Israeli-style measures, which are the strictest in the world and create a perimeter around the airport.
“Our security is excellent in the United States,” Casel told Inside Edition. “I think it can be improved.”
He believes that travelers will begin to see their cars getting checked.
“Instead of fixed check points, we are going to see pop-up, random check points,” he said.
