Md. Aid Workers Narrowly Avoid Deadly Brussels Explosions

BALTIMORE (WJZ) -- A massive investigation is underway into twin terror attacks in Brussels. Four suicide bombers, including two brothers, carried out the bombings. The only terrorist to survive is on the loose.

Belgium is in mourning. The toll from the blasts stands at 31 dead and 300 injured.

Tracey Leong has more on the U.S. victims.

Across the country, Americans face heightened security in the wake of the terror attacks in Brussels. Several families here at home also face the agony of worrying about loved ones who are missing or were hurt in the attacks.

When terrorists bombed Brussels airport, Kentucky native Carolyn Moore was with her daughter, Stephanie. Stephanie is now missing.

"My husband called the American Embassy, and they're looking for her too," said Moore.

Three American Mormom missionaries were also at the airport; Richard Norby, Joseph Empey and Mason Wells were all hurt.

American college students Kate Duffy, Lauren Cleary and Monica Hall narrowly escaped the airport bombings.

They're all safe, despite the close call, and vow to continue their trip through Europe.

"She's telling us she's planning on continuing her trip because she said if she doesn't, they win, so she's going," said Judy Duffy, mother.

Maryland Jhpiego aid workers were also caught in the violence.

Julia Bluestone (above) had just passed through the airport minutes before the explosions.

Denise Brandt, following behind, was just feet from the bombs.

"She found a direction to exit and worked towards exiting. Of course, she was told she had to leave everything behind," said Leslie Macuso, president, Jhpiego.

Mancuso tells WJZ Brussels is a common airport to travel through during their missions around the world and the threat of terrorist attacks will not stand in their way to help others.

"Continue to make us equally vigilant about our travels and making sure that our staff are prepared," she said.

Jhpiego is affiliated with Johns Hopkins University. The nonprofit works in more than 40 countries around the world.
