Pictures from the scene showed smoke pouring from the terminal and passengers fleeing the area. "There was an explosion … there are several dead and wounded but we can't say how many at this point," a federal police spokesman said.
A security source told NBC News the explosion happened near check-in desk four but it was not immediately clear if terrorism was involved. The explosion comes amid a flurry of counter-terrorism activity in the Belgian capital.

A raid this week in Brussels captured Europe's most wanted man — Salah Abdeslam, suspected Paris terror attacks plotter and aborted suicide attacker. Abdeslam was taken into custody along with several others. His capture has been seen as a potential goldmine of information for intelligence services — if he cooperates.
The 26-year-old and several of the attackers who laid siege to Paris on Nov. 13 had ties to Belgium.
Firefighters report 11 dead and 25 wounded in the airport explosions.
