At least 28 people have been killed and 60 others injured in the attack at Istanbul’s Ataturk Airport, Turkey’s Justice Minister Bekir Bozdag told CNN.

The two suicide bombers were also killed. Bozdag said one attacker “first opened fire with a Kalashnikov then detonated himself” at the airport entrance.

In total two bombs exploded. One of them was located just outside the terminal on the pavement, the other was at the security gate at the entrance to the airport.

Authorities said no bombs exploded within the airport building itself, according to the minister.

A Turkish official told CNN that police fired shots at suspects near the international terminal in an effort to neutralize them.

Videos posted on social media show travelers sitting on the airport floor. A man shouts, “Get down! Get down!” Someone cries as a gunshot rings out.

The attacks happened on a warm summer night at the airport, east of Istanbul, that is the 11th busiest in the world in terms of passenger traffic. CNN’s Ali Veshi says it is a modern, sophisticated airport. “There are all of the major European and American boutiques there,” said Velshi, who has traveled through Turkey many times.

“… You see people of all shapes and colors, in all sorts of dress. If you want to target the cosmopolitan nature of Istanbul, this is possibly the most cosmopolitan, heavily populated part. You can target tourist areas, but this is the part where the world comes together.”
