At least 41 people were killed and 239 more wounded in two explosions that rocked Istanbul’s Ataturk International Airport late Tuesday.
The Turkish government also said at least 10 foreigners are among the dead.
Government officials had initially reported 50 people were killed in the attacks, but withdrew that estimate early Wednesday morning.
No one has claimed responsibility for the deadly attack, but Turkish Prime Minister Binali Tildirim says he suspects the Islamic State is behind the attacks that involved three bombers, all of whom have been confirmed dead.
The attack came two years after the Islamic State declared a caliphate spanning Syria and Iraq.
Turkish Justice Minister Bekir Bozdag told the AP, “a terrorist at the international terminal entrance first opened fire with a Kalashnikov and then blew himself up.” Another official said the attackers set off their explosives after police engaged them.
The explosions occurred at the international arrival terminal at Ataturk Airport, according to a national TV station. Other news outlets reported onlookers heard gunfire, but government officials have not confirmed those stories.
One eyewitness said 30 ambulances were dispatched to the scene to transport the wounded to the local Bakirkoy State Hospital. Law enforcement officers were among those injured.
U.S. authorities suspended all flights to or from Turkey through most of Tuesday evening. The ban was lifted early Wednesday morning local time.
A plane carrying Albanian Prime Minister Edi Rama had been landing at the airport at the time of the attack. Rama was immediately secured and officials do not believe he was the target of the attacks.
While Turkey has endured a number of bombings by Islamic State militants in recent months, Tuesday’s attacks come hours after Israel and Turkey signed a deal to normalize diplomatic relations after a six-year split.
Various European Union leaders have condemned the deadly attack. The 28 continental leaders had gathered for an impromptu discussion regarding how to handle Britain’s decision to leave the union, as well as concerns about refugees migrating through Turkey.
The U.S. Embassy is working to identify whether any Americans are among the victims of Tuesday’s attack. There is currently a page to help travelers. The U.S. State Department had also issued a travel warning for Turkey just a day before the attack.
Ataturk is the largest airport in Turkey and the third busiest in the continent. In 2015, the airport had more than 41 million travelers pass through, according to the airport’s website.
