killing at least 36 people

and leaving almost 150 injured.

Witnesses claimed,

one of the three attackers opened fire with an automatic weapon,

causing bystanders to flee in panic

before all three blew themselves up.

Although no one has yet claimed responsibility for the attack,

Turkish officials blamed terrorist group Islamic States,

also known as ISIS (Daesh).

Police shot at two of the attackers as they tried to pass through a security check point in the arrival zone.

But they still managed to detonate their bombs

The attack is the fourth deadly bombing in Istanbul in the past six months.

And was similar to the recent ISIS assault at Brussels airport in Belgium

where 16 people died.
