Pray for Belgain

Day broke Wednesday on a Brussels facing a new reality, and a new identity as a city contorted by grief but sustained by a shared determination to carry on.And it was a day, of course, when the Belgian capital indeed, the European capital -- was more acutely aware than ever of its vulnerability.

Twin explosions Tuesday at the city's main airport, and then another one at a downtown subway station, killed 31 people and injured 270 others. But what option is there, residents asked, other than to continue to work and to live as normally as possible?

"You can feel the fear on the streets today," said Souheil, 21, who was taking the train Wednesday morning to his internship at the European Commission, near where the explosion at the Maelbeek metro station detonated Tuesday. "But you can also see that people want to fight it. It's a good thing."

As Belgium mourns and Brussels struggles back toward some semblance of normality, new details emerged about the attacks.

Prosecutor Frederic Van Leeuw identified Ibrahim El Bakraoui as one of the airport suicide bombers and his brother, Khalid El Bakraoui, as the man behind the deadly suicide blast near the metro station.

ISIS has claimed responsibility for the Brussels and Paris attacks -- raising concerns that the terror group is gaining more traction in Europe.
