Victims of the Brussels attacks
Victims of the Brussels attacks included commuters and travellers from around the world.
Here are details of some of those confirmed dead.
:: Gigi Adam's 79-year-old father Andre died trying to protect his wife during the airport attack. The retired Belgian diplomat had served as his country's ambassador to Cuba, the United States, the United Nations and other countries.
"His death has wounded us all forever," Gigi Adam wrote on Facebook. "All his life he had worked towards the peaceful resolution of conflict in the world."
:: American couple Justin Shults, 30, and his wife Stephanie who had not been seen since Tuesday's attacks, have now been confirmed as victims of the airport bombings.
Mr Shults, originally from Gatlinburg, Tennessee, and his wife, a Lexington, Kentucky, native, graduated together from Vanderbilt University's Owen Graduate School of Management. They were dropping Mrs Shults' mother off at the airport and watching her walk through security when the bombs went off, a family member said.
Mr Shults' brother, Levi Sutton, sais Justin "travelled the world, leaving each destination better than when he arrived".
:: Patricia Rizzo's family hails from a tiny town in Sicily, but she was as broadly European as they come.
Ms Rizzo, 48, was among the dead from the attack on Maelbeek station.
She returned to Italy from 2003 to 2008 to work as the assistant to the executive director of the European Food Safety Authority and in 2008, she was named human resources assistant for the EU's education and culture agency in Brussels. For the past five months had worked in the human resources department of the European Research Council.
Born in Belgium to a family originally from Calascibetta, near Enna, Sicily, she graduated from a Belgian university and worked for several Belgian companies as an executive secretary before joining European institutions in 1995.
"After a few days of excruciating waiting and angst, our worst fears have been confirmed," the ERC's executive leadership said, praising Ms Rizzo's energy, attitude and spirit.
Ms Rizzo is survived by a son and her parents.
:: Jennifer Scintu Waetzmann was a coach for a youth handball club in Aachen, Germany.
Her uncle, Claudio Scinto, told the German newspaper Bild that she and her husband were checking in at Brussels airport en route to a belated honeymoon in New York when the first bomb exploded.
The blast killed her and left her husband, Lars Waetzmann, among the 270 wounded.
Her final post on Facebook came right after the November extremist assaults on Paris. It said: "Pray for Paris." Other pictures show her and her husband in romantic seaside settings with the inscription: "Love of my life."
German interior minister Thomas de Maiziere said his thoughts were with her family and vowed Germany "will not rest until the murderers and those who aided them are held responsible".
:: Elita Borbor Weah, 40, who was heading to Rhode Island, New York, for her stepfather's funeral, had texted family members a photo of herself at the airport.
She had been living in the Netherlands with her 13-year-old daughter after her extended family from Liberia had dispersed across west Africa, Europe and the United States following Liberia's civil wars.
"She had a good heart," said her 14-year-old niece Eden Weah. "She was always worried about everybody."
:: David Dixon had texted family members to say he was safe after two bombs severely damaged the airport, but he was killed shortly afterwards when a bomber attacked the Metro system.
Mr Dixon, 50, a British citizen originally from Hartlepool , was working as a computer programmer at the time of his death. Press reports indicated he lived in Brussels with his partner and their son.
Prime Minister David Cameron said he was "deeply saddened" by his death.
:: Brother and sister Alexander and Sascha Pinczowski, Dutch nationals who lived in New York City, were heading home when a bomb exploded at the airport. Alexander, 29, was on the phone with his mother in the Netherlands when the line went dead, said James Cain, whose daughter Cameron was engaged to Alexander.
Alexander had travelled to the Netherlands to work on a craft-related business that he and Cameron were going to start together.
In November, Sascha Pinczowski, 26, had warned that demonising Muslims would help drive the recruitment of extremists. She posted on Facebook after the November 13 Paris attacks that "ignorant spreading of anti-Muslim sentiment and propaganda does nothing but benefit Isis".
Her message was reposted by her mother, Marjan Pinczowski Fasbender, who said she wanted to share "this message of tolerance from our Dear Daughter Sascha".
:: The Chinese embassy in Belgium said a Chinese national was killed in the attacks. He was identified only by his surname, Deng.
:: Peruvian-born Adelma Tapia Ruiz, 37, dreamed of opening a restaurant. She had lived in Belgium for nine years but still cooked the recipes of her homeland, preparing the spicy chicken dish aji de gallina for a food festival organised by the Peruvian consulate in Brussels last year.
The mother of two, who about to fly to New York to meet two sisters, was killed when a bomb tore through the airport's departures area. But a split-second decision saved her husband and four-year-old twin daughters Maureen and Alondra from sharing her fate.
Christophe Delcambe had taken the girls out of the check-in line to play for a moment when the explosion ripped through the concourse. One daughter was struck in the arm by shrapnel and is being treated in hospital.
:: Leopold Hecht, 20, gravely wounded in the Maelbeek bombing, died later of his injuries.
Classmates at Saint-Louis University in Brussels lit candles and left flowers outside the university in memory of Mr Hecht, whose Facebook profile includes pictures of a smiling young man on the ski slopes and in the great outdoors.
:: Civil servant Olivier Delespesse died in the bombing at Maelbeek station, according to his employer, the Federation Wallonie-Bruxelles.
