Thirty seven victims have already been identified, the Turkish authorities said.
"It was determined that 41 people lost their lives. Thirty seven people of those killed have been identified, 10 of them foreign nationals, while 3 were found to be dual citizens," the Istanbul governor’s office said in a press release.
Several suicide blasts hit the entrance, exit and a parking lot of the airport's international terminal at about 10 p.m. local time (19:00 GMT).
Following the blasts, the Istanbul airport was totally evacuated and closed. Hundreds of flights were canceled. However, Yildirim, who attended the scene of events, said later that the airport had resumed its air traffic in a normal mode. Russia’s flagship airline Aeroflot canceled flights to and from Istanbul's Ataturk international airport on Wednesday.
Sputnik’s source said Chinese, Saudi, Iranian, Iraqi, Tunisian, Jordanian, Ukrainian and Uzbek nationals were among those killed late Tuesday.
