Turkey has observed a national day of mourning after a gun and suicide bomb attack on Istanbul's Ataturk airport killed 42 people, including 13 foreign nationals.
Three attackers arrived in a taxi and began firing at the terminal entrance late on Tuesday. They blew themselves up after police fired back.
Officials earlier said 239 people were injured, with 41 in intensive care.
PM Binali Yildirim said early signs pointed to so-called Islamic State.
CIA Director John Brennan also said it "bears the hallmarks" of the jihadist group.
However, no-one has so far admitted carrying out the attack.
