The attack on the main Istanbul airport is just the latest of several bombings to have hit Turkey in recent months.
Many of the attacks appear to have targeted tourists, who are a major contributor to Turkey's economy. They include two in Istanbul, which authorities have blamed on ISIS.
There was no immediate claim of responsibility after Tuesday's blasts, which killed at least 36 people, but Prime Minister Binali Yildirim said they appeared to have been carried out ISIS.

On March 20, Turkey's interior minister identified a suicide bomber who killed himself and four foreign tourists as a militant with links to ISIS. The victims were two American-Israelis, another Israeli and an Iranian.

And on Oct 10, the deadliest attack in modern Turkish history killed at least 102 people and injured 248 others when two suicide bombers detonated explosives in their vests outside a train station during a pro-Kurdish rally in Ankara. U.S. intelligence officials said the attack was directed by ISIS.
Turkey is part of the U.S.-led coalition fighting ISIS, but it has also been clashing with the outlawed Kurdistan Workers Party (PKK) since a two-year cease-fire collapsed in July.
PKK, which says it is fighting for autonomy for Turkey's large ethnic Kurdish minority, is considered a terrorist group by Turkey, the United States and the European Union.
It has been targeting police and military personnel with bombs since the peace process collapsed last year, while Turkey has been staging regular airstrikes against PKK positions in mountainous northern Iraq, where it has camps near the Turkish border.
The decades-long conflict has killed more than 40,000 people.
