U.S. Secretary of State John Kerry, meanwhile, announced he is coming to Brussels on Friday to talk with European officials about fighting terror.
An official in the Turkish president's office says the Brussels attacker who was deported from Turkey was Ibrahim El Bakraoui.
The official corrected Turkish President Recep Tayyip Erdogan's account, saying El Bakraoui, who was caught in June at the Turkish-Syrian border, was deported to the Netherlands in July, not Belgium.
Turkey says it warned both Belgium and the Netherlands that he was a "foreign terrorist fighter."
The official says Dutch authorities laterallowed him to go free because Belgian authorities could not establish any ties to terrorism. The official cannot be named because he was not authorized to speak publicly on the issue.
A Belgian prosecutor says El Bakraoui was a 29-year-old Belgian who blew himself up at the Brussels Airport on Tuesday.

Turkish President Recep Tayyip Erdogan says one of the Brussels attackers was caught in Turkey in June and deported to Belgium.
Erdogan says Wednesday that the Belgian authorities released the suspect despite Turkish warnings that he was "a foreign fighter."
Erdogan did not name the attacker. He said the man was detained at Turkey's border with Syria at Gaziantep and that Turkey formally notified Belgian authorities of his deportation on July 14.
Erdogan says "despite our warnings that this person was a foreign terrorist fighter, Belgium could not establish any links with terrorism."
Neighbors of two brothers who committed suicide attacks in Brussels are expressing shock and bewilderment at what happened.
John Valderrama lived across the hall from the brothers in the Schaerbeek neighborhood, but says he never heard anything suspicious. He said he only saw one person come in or out of the fifth-floor apartment.
He was surprised when hours after Tuesday's attack, police burst into the brothers' apartment, where they discovered a large cache of TATP explosives.
Valderrama says "when I saw them I went `Whoa!"
Another neighbor, Erdine, said he was about to drive his son to school around 7:30 a.m. Tuesday when he saw two people carrying heavy bags out of the building.
The 36-year-old, who declined to give his last name due to the situation, says he saw a cab driver open his trunk. He says "the taxi driver tried to get the luggage. And the other guy reached for it like he was saying, `No, I'll take it."'
Prosecutors say the taxi driver tipped them off to the Schaerbeek address after the attacks.

The resolution also expresses condolences to those affected by the attacks.
French Prime Minister Manuel Valls says one of the lessons learned from yet another attack in a European Union nation is that the bloc's 28 nations must heavily increase their investments in anti-terror measures.
Valls told reporters "in the coming years, EU nations will have to invest massively in their security system." He spoke after meeting with EU Commission President Jean-Claude Juncker in Brussels.
Valls mentioned specifically that more funds will be needed for "manpower, technology -- to face the types of threats that we will have to face."

He says "it's a moment for all member states to start working together. To foster mutual trust, exchange information and intelligence, because this is the only way to go ahead."

Dozens gathered for a moment of silence outside the European Commission, hoping to show solidarity with the victims of the Brussels attacks and be with their fellow citizens in a time of crisis.
Among them was Alessandro Prister, 56, who works for Eurocontrol. He says Wednesday that he "felt it was my duty to show solidarity with all the victims" and to offer testament that this kind of attack should never happen again.
Prister was saddened that such things could happen in Brussels and says "I couldn't be any other place today."
Belgium's chief prosecutor says investigators have found 15 kilograms (33 pounds) of TATP explosives at the house which the suspects in the Brussels attacks left from for the airport.

He says a special squad found the explosives inside the house, along with other chemicals that are commonly used to make bombs.
Explosions on Tuesday at the Brussels airport and a city subway center killed 34 people, including three suicide bombers, and wounded over 270 people.
The Belgian prosecutor says two suspects in the bombings at the Brussels airport have still not yet been identified -- one of them is a dead suicide bomber and the other is still on the loose.
Prosecutor Frederic Van Leeuw, speaking about a surveillance photo showing three airport suspects, outlined what is known about them at a news conference Wednesday.
Van Leeuw says the culprit in the middle, one of the two suicide bombers, was Ibrahim El Bakraoui, a 29-year-old Belgian born in Brussels. He said he was identified based on a fingerprint.
He says the second suicide bomber, on the left in the picture, is not yet identified.
The third suspect, who wore a pale coat and a dark hat in the right side of the picture, is also not yet identified and is being sought by police.
That suspect took flight and left behind a big bag at the airport before the two explosions. Van Leeuw says that bag turned out to have the heaviest load of explosives of all and blew up later when the bomb squad was there due to the instability of the explosives. Van Leeuw says fortunately no one was injured.
Belgian authorities say several people possibly linked to deadly attacks on Brussels are still on the loose.
Paul Van Tigchelt, head of Belgium's terrorism threat body, told reporters Wednesday that is why the country is keeping the terrorism threat level at its highest level, which means there is a danger of an imminent attack.

Brussels airport has announced that it will remain closed to passenger flights for at least another day, right up to the start of the busy Easter weekend.
Airport officials said they would have to cancel some 600 flights each on Wednesday and Thursday. It means that since the attack on the airport Tuesday morning, the flights of some 180,000 passengers will be disrupted.
Brussels airport was hoping to resume cargo flights earlier but there was no immediate word on when.
Belgians are holding a moment of silence to honor at least 34 people killed in unprecedented Islamic extremist attacks on Brussels.
Government offices, schools and residents marked the moment in a mood of anxiety, defiance -- and fear that other people involved in the attacks Tuesday on the Brussels airport and a subway station may still be at large.
The country is holding three days of national mourning for the victims. In addition to those killed, over 200 people were wounded in the attacks.
Belgian police, meanwhile, are conducting raids and the country is at its highest terrorism alert level, meaning there's a risk of an imminent attack.

The federation said "because of security concerns" the city of Brussels asked for the cancellation and the federation obliged. The game was to have been played next Tuesday at the King Baudouin stadium in Brussels.
The Belgian team, which is one of the favorites to win this summer's European Championships, had already canceled training for the friendly since the attacks.
French Prime Minister Manuel Valls says the show must go on and big events, be they sports or cultural, mustnot be put on hold for fear of terror attacks.
He says Wednesday that includes the Euro2016 soccer tournament, a monthlong event being held in France that starts in June.
Valls says "the big popular events are indispensable in showing that we are a free people, on our feet, that we aren't scared."
Some commentators had called for the soccer tournament to be postponed due to the threat of terror.
Valls says authorities know these events are faced with a terror threat and will plan accordingly. But he insists that events like the Euro2016 tournament, the Tour de France bicycling race and "other large demonstrations will take place."

A lawyer's assistant says a judicial hearing in Brussels for Paris attacks suspect Salah Abdeslam has been postponed for a day to Thursday, apparently because of heightened security concerns in the Belgian capital.
Bombing attacks Tuesday in the Brussels airport and subway killed 34 people and wounded scores, and the terrorism alert level throughout Belgium has been raised to its maximum level.
Abdeslam, who was arrested Friday in Brussels, was to appear Wednesday before a panel of judges who could extend his detention by another month. French authorities are seeking Abdeslam's extradition so he can be tried for his alleged role in the Nov. 13 bomb-and-gun attacks that killed 130 in Paris.
An assistant to Sven Mary, Abdeslam's defense lawyer, told The Associated Press her boss was told the hearing had been rescheduled for Thursday morning. She refused to give her name.
French Prime Minister Manuel Valls is urging the EU parliament to get going on authorizing a passenger name record (PNR) covering Europe.
He says: "It is urgent to adopt the European PNR. The European Parliament has waited too long to adopt this text. It must examine and adopt it in April, it's time."
Valls is going to Brussels today and says he will express his "full solidarity" with Belgium's people.
As Brussels woke after its worst violence in decades, joggers ran loops and dog walkers chatted as usual in Brussels' 18th-century Warandepark across from the country's parliament. But gardeners on duty said the atmosphere was different, and the mood around town was jittery as sirens frequently wailed.
"It was black day. A very black day," said Jean-Marie Vrebos, 58, who was cleaning the park's playground. "We should punish those who commit terrorism. We don't deserve terror. We should punish them, GRAB them" -- he yanked a piece of trash off the ground with a clasper -- "and bring them to justice."
His colleague Kevin Engels, 24, said, "Behaviors have changed. Even our bosses seem stressed. They asked us to empty all the trash cans. We pay close attention to everything. And you can hear the sirens."
Germany's top security official says he wants European security agencies to be able to exchange information more easily.
Interior Minister Thomas de Maiziere told RTL television late Tuesday that the Brussels attacks "and the security situation, the terror situation, should make us put the data protection arguments last."

In November, Islamic extremists tried to enter the stadium where Germany was playing France as part of a series of attacks in Paris. Days later, a friendly against the Netherlands days was canceled because of a security warning.
Belgian authorities were searching Wednesday for a top suspect in the country's deadliest attacks in decades, as the European Union's capital awoke under guard and with limited public transport after 34 were killed in bombings on the Brussels airport and a subway station.
Police conducted raids into the night and circulated a photo of three men seen in the airport suspected of involvement in Tuesday's attacks.
Belgian state broadcaster RTBF has identified two of the attackers as brothers Khalid and Brahim Bakraoui. They are believed to have blown themselves up in the attacks.
The third man is at large and has not been identified.
The report Wednesday says the brothers were known to police for past crimes, but nothing relating to terrorism. RTBF says Khalid Bakraoui had rented an apartment which was raided by police last week in an operation that led authorities to top Paris attacks suspect Salah Abdeslam.
