The third gunman was reported to have blown himself up in the car park outside.Prime Minister Binali Yildirim said so far all indications pointed to the Isis group being behind the attack.The Turkish news agency Dogan reported that the Albanian Prime Minister, Edi Rama, was landing at the airport for an official visit when the attack took place. Details are still emerging about the nationalities of those killed and injured.
Secretary-General Ban Ki-moon has condemned the "terrorist attack" at Istanbu's Ataturkl airport and is calling for the perpetrators to be identified and brought to justice.
The Belgian prime minister, Charles Michel, has also condemned the bombing.
"What is noteworthy is that this attack came at a time when our country is putting up a merciless fight against separatist terrorism and recording significant success,” Mr Yildirim said.
Some flights have now resumed at the airport, including the lifting of a blanket ban on all flights to and from the US.
He said the attackers arrived at the airport in a taxi, and they were able to launch the attack without going through security checks. Asked about Turkish media reports of a fourth gunman who escaped, he said they had no evidence of that but were not ruling anything out at this stage.
"This (attack) has shown once again that terrorism is a global threat," he said.
"This is a heinous planned attack that targeted innocent people." "The findings of our security forces point at the Daesh organisation as the perpetrators of this terror attack," Mr Yildirim told reporters at the airport, using another name for Isis.
"Even though the indications suggest Daesh, our investigations are continuing.
Turkish officials say initial investigations point to Isis being behind a triple suicide bombing and gun attack on Istanbul’s Ataturk international airport which killed at least 41 people.
Another 239 people were injured, many seriously, after three gunmen armed with AK-47s opened fire on passengers. CCTV footage shared on social media showed two of the detonations, at least one of which came after police officers fired on and wounded an attacker.
