Brussels remains under a maximum terror threat for a second day.
On Sunday, police told residents to avoid windows, especially those near the capital's main square Grand-Place as a new operation began.

There is some speculation that he didn't blow himself up as instructed and that ISIS could also be looking for him.
But the concern is not just for Abdeslam. Belgium Prime Minister Charles Michel is reportedly worried that attacks like those in Paris could happen in Brussels. (Video via The Telegraph)
"Brussels is at a level 4, but we're going to keep a secure presence all over the country," said Michel during a press conference Saturday. (Video via MSNBC)
The Belgian capitol was quiet Sunday, as trains, shops and schools were closed. Belgian troops have joined police to help patrol areas of concern, especially key intersections.
