Prime Minister Binali Yildirim says that so far all indications point to the Islamic State group being behind the attack. He says the attackers arrived at the airport in a taxi and blew themselves up after opening fire.
Asked whether a fourth attacker might have escaped, he says authorities have no such assessment but are considering every possibility.
He says the victims include some foreigners and that many of the dozens wounded have minor injuries but others are more badly hurt.
He says the attacks come as Turkey is having success in fighting terrorism and trying to normalize ties with neighbors like Russia and Israel.
White House spokesman Josh Earnest says the United States condemns in the strongest terms possible the attacks.
Earnest says the Istanbul airport, like the Brussels airport that was attacked earlier this year, is a symbol of international connections and the ties that bind nations together.
He says the U.S. sends its deepest condolences to the families and loved ones of those killed and wishes a speedy recovery to those injured.
Earnest says the United States remains steadfast in its support for Turkey, a NATO ally and partner, "along with all of our friends and allies around the world, as we continue to confront the threat of terrorism."
