UPDATED June 29 10:35 a.m. PT

At least 41 people are dead after several attackers blew themselves up at Istanbul's Atatürk Airport at around 10:15 p.m. local time Tuesday, according to Turkish officials and local media. Dozens more were injured in the attack at the airport, which is the busiest in the country and the third busiest in Europe.

Justice Minister Bekir Bozdag initially confirmed a death toll of 10 to Turkish media. "According to the information I was given, a terrorist at the international terminal entrance first opened fire with a Kalashnikov and then blew himself up," he said, according to Turkey's state-run news agency. "We have around 10 martyrs [deceased] and around 20 wounded."

That count has since been updated to 41, with hundreds injured, the Associated Press reports.

While two people were initially believed to be involved in the attack, governor Vasip Sahin has since told Turkish news channel NTV that there were three suicide bombers.

An official told the Associated Press that two of the attackers detonated the explosives at the entrance of the international terminal before entering the X-ray security check, while a third blew himself up in the parking lot.

A senior government official told the Associated Press that early indications suggest that Islamic State (ISIS) is behind the attack.

Gunfire was heard from the car park area of the airport, Sky News reports. Taxis took injured people away from the scene.

The U.S. consulate said Tuesday it was working to determine if any U.S. citizens were among the victims. Facebook, meanwhile, activated a Safety Check following the attack.

Some flights continued to land shortly after the explosions, but many more were diverted to other airports in Turkey and the airport eventually closed.

A BBC journalist, who was detained on a plane at the airport as events unfolded, said the incident had the hallmarks of a large and coordinated attack.

Recent attacks in Turkey have been claimed by either Kurdish separatist groups or ISIS.

Turkish President Recep Tayyip Erdogan released a statement condemning the attack, which took place during the Muslim holy month of Ramadan. He says the attack "shows that terrorism strikes with no regard to faith and values".

He called on the international community to take a firm stand against terrorism and vowed to keep up Turkey's struggle against terror groups.

"Turkey has the power, determination and capacity to continue the fight against terrorism until the end," he said.

The White House, meanwhile, condemned the "heinous terrorist attack."

Istanbul's Ataturk airport was the 11th busiest airport in the world last year, with 61.8 million passengers, according to Airports Council International. It is also one of the fastest-growing airports in the world, seeing 9.2 percent more passengers last year than in 2014.

The largest carrier at the airport is Turkish Airlines, which operates a major hub there, followed by low-cost Turkish carrier Onur Air.
