Reports said there were screams as the terrorists fired and bombed in one of the busiest airports of the world and third busiest in Europe.

Turkish Prime Minister Binali Yıldırım confirming the toll at 36 has said militant group ISIS is suspected to be behind the attack.

The prime minister was quoted as saying that three attackers arrived in the airport on a taxi cab and also used guns during the attack.

He said the three men exploded themselves, adding "this attack, targeting innocent people is a vile, planned terrorist act." The terrorists opened fire in the departures hall too as people ran for cover. 

Indian Prime Minister Narendra Modi  condemned the suicide attack calling it ' inhuman & horrific'.

Condemning the attack, Modi tweeted, "Attack in Istanbul is inhuman & horrific. I condemn it strongly. My thoughts are with bereaved families. May the injured recover quickly."

Faced with terrorism on its soil, Turkish President Recep Tayyip Erdogan said the attack should be seen as a turning point in the global fight against terrorism.

"The bombs that exploded in Istanbul today could have gone off at any airport in any city around the world," he said, quoted BBC.
 
Belgium Prime Minister Charles Michel tweeted: "Our thoughts are with the victims of the attacks at Istanbul's airport. We condemn these atrocious acts of violence."

"Our deepest condolences go out to the families and loved ones of those killed, and we wish a speedy recovery to those injured. We remain steadfast in our support for Turkey, our NATO ally and partner, along with all of our friends and allies around the world, as we continue to confront the threat of terrorism."
