Peru's foreign ministry has confirmed to the BBC that Adelma Tapia Ruiz is one of the victims of the Brussels airport bombing.
The mom, who was in her late 30s, was at the airport with her husband, Christophe Delcambe, and their twin girls, Maureen and Alondra. They were catching a flight to New York to visit family.
According to her brother, Fernando Tapia Coral, the four-year-old girls went outside the gate area to play moments before the explosion. Their father followed them. The three survived the blast, although Maureen and her dad were injured.
"They took away everything she wanted to do with her life," Tapia told media.
"It's very complicated to describe this pain that we're feeling at home, but as an older brother I know that I have to do it," Tapia wrote in a Facebook post. "But even more incomprehensible is not being able to be close to her. And this tragedy today touched the doors of my family this morning in the Brussels airport when my sister Adelma Tapia died in the terrorist attack."
Adelma Tapia Ruiz is among the 31 people who died in the attacks at the Brussels' airport and metro station on Tuesday. Another 270 are recovering from injuries.
