Warning: This video contains footage that may disturb some viewers CCTV footage captured the moment a police officer tried to stop one of the gunmen at Istanbul Ataturk airport in an attack that left 36 dead and 150 injured.
The triple suicide bombing in Turkey's main international airport on Tuesday night (local time) saw suicide bombers detonate explosives vests in the arrivals hall.
They had been trying to pass through security when they were stopped by officials. They began to shoot with AK-47 rifles and they were met with return fire from officers.
One officer tried to tackle the assailant when he detonated his device in sync with the other two suspects.
An organisation is yet to claim responsibility for the attack. Turkey's Prime Minister Binali Yildirim said ISIL is the most likely suspect.
ISIL had called for attacks during the holy month of Ramadan with a focused attention on Turkey, which is currently attempting to join the European Union.
British Prime Minister David Cameron has described the attack at Istanbul Ataturk airport that killed 36 and injured 150 as "hideous".
Mr Cameron in Brussels for likely his last European Union summit meeting said after Brexit the UK would continue to work with other countries on "keeping our countries safe, keeping our people safe - and it's particularly important to say that tonight again when there has been another hideous terrorist attack in Turkey".
More than two million Britons travel to Turkey each year, although this has seen a decline amid recent terrorist attacks.
