The three suicide bombers who struck Istanbul's Ataturk Airport on Tuesday came from Chechnya, Uzbekistan and Kyrgyzstan, AP reports. 

Amy Kellogg brought us the latest details this morning on Fox and Friends, explaining that one of the bombers is being identified in reports as Osman Vadinov, who is known to be an ISIS fighter.

Vadinov is said to have crossed into Turkey from the ISIS capital of Raqqa, Syria, in 2015.

Kellogg said it's rare to hear of terrorists coming from former Soviet republics into Europe to commit attacks on behalf of ISIS.

She said that if it's confirmed that Vadinov was one of the attackers, "it would be further confirmation that ISIS was behind these attacks." 

Kellogg said the bombers reportedly rented an apartment in Istanbul 33 days ago, paying cash and installing an extra security gate. Other reports have indicated there were strange smells coming from the apartment.

Earlier this morning, Turkey’s state-run news agency said police detained 13 suspected militants, including three foreign nationals.

The attack, which killed 44 people and wounded more than 200, has been blamed on ISIS, but the group has not claimed responsibility.
