Migration Crisis Looms in Background of Brussels Terror Attacks

Belgium officials rushed to restore a sense of security on Tuesday in the face of a horrific string of terror attacks that have left at least 31 dead and dozens more injured.

Authorities responded by freezing all public transport flowing into the heart of Brussels and implementing checkpoints at sections of the border.

But working on the backdrop of the emergency response are growing concerns of potential cracks in security from yet another ongoing crisis — a massive migration wave that has made it all but impossible for countries to monitor who comes and goes.
