A southeast Texas native and wife of an Air Force officer was one of the people killed in the Brussels attacks, a US congressman said on Wednesday.

Gail Minglana Martinez, 41,was identified as a victim by the office of US Rep Blake Farenthold, who said in a statement that he had spoken to Martinez's brother.

Suicide bombers killed 32 people at Brussels' airport and in a subway station near the European Union headquarters. Dozens of people remain hospitalized.

Martinez was married to Lt Col Kato Martinez, who Farenthold said is still hospitalized due to the blast, as are the couple's four children.
