The explosions that went off early Tuesday morning at Brussels Zaventem airport and Maelbeek metro station left more than 30 dead and injured dozens of others, the BBC reported.

The University issued a similar statement in November after the attacks in Paris, when 52 GW students were studying abroad in the city.
