Istanbul explosion: Airport is third largest in Europe

Istanbul Ataturk Airport, where explosions and gunfire were reported Tuesday, is the third largest airport in Europe, serving some 61 million travelers in 2015.

The airport is 15 miles west of Istanbul and was built in 1924. The airport has been expanded and modernized through the years and now is the 11th busiest airport in the world.

It was named after Mustafa Kemal Ataturk, the founder and first president of the Republic of Turkey. It is an airport of last departure, meaning there are direct flights between the airport and cities in the United States and other countries.

After the explosions, reportedly caused by suicide bombers in a departure area, the airport closed several gates, and flights are being rerouted, or canceled. At least 10 people are dead, according to Turkish officials.

Update at 5:30 p.m. ET - The FAA has canceled all flights between the United States and Istanbul.
