Turkish government officials on Thursday identified the bombers behind the attack on Istanbul’s main airport as nationals from Russia, Uzbekistan and Kyrgyzstan, according to an Associated Press report.

The government also detained 13 people including three foreign nationals in connection with Tuesday’s attack following raids across Istanbul, the AP reported.

The attackers arrived at Istanbul’s Ataturk Airport late on Tuesday and opened fire before blowing themselves up when police responded. A total of 42 people were killed and more than 200 more wounded. No terrorist group has claimed responsibility but security experts have said the attacks was likely conducted by ISIS militants.
