The ongoing investigation into the suicide attacks carried out at Ataturk International Airport in Istanbul has revealed the identity of the three suicide bombers who carried out the triple attack on Tuesday.

Investigators in Istanbul said that of the attackers who blew themselves up in front of Ataturk International Airport and in the Turkish Airlines lounge, one was of Daghestani origin and is a Russian national, the second is a Kyrgyzstan national and the third is from Uzbekistan. Investigative authorities are still trying to obtain the names of the three terrorists after it appears that ISIS was responsible for the attack on Istanbul’s main airport.

On his part, the Turkish Prime Minister Binali Yildirim reiterated that security investigations into the terrorist attacks at Ataturk Airport indicate that ISIS is responsible for carrying them out despite the fact that the investigation is ongoing.

According to informed Turkish sources, the authorities are having difficulty in identifying the three terrorists’ names because their bodies were blown to pieces and only their lower body parts remain. However, the Hürriyet daily newspaper quoted sources from the investigation as saying that one of the three suicide bombers who were found dead at the scene was called Osman Vadinov and that he was a Chechen of Russian origin who had come from the ISIS controlled city Raqqa in Syria.

As part of the current investigations into the suicide attack which left 43 people dead and 238 injured, Turkish police have arrested 13 people. Those arrested in simultaneous raids on houses and sites in the cities of Istanbul and Izmir on Thursday morning include three foreigners, and security sources said that they are nationals of former Soviet Republics.
