Brussels to remain on maximum alert, Belgian PM says

The city of Brussels will remain on its highest level of alert on Monday while the rest of Belgium will stay at the second-highest threat level due to the continuing possibility of terrorist attacks, Belgian Prime Minister Charles Michel said Sunday.
"What we fear is an attack similar to the one in Paris, with several individuals who could also possibly launch several attacks at the same time in multiple locations," he said at a press conference, adding that additional policemen and troops will be deployed in the capital.
Brussels has been under lockdown at level four since Saturday, with the rest of the country at level three amid a continuing manhunt for jihadist terror cells including at least one of the perpetrators of the assault on Paris. A large portion of the Belgian capital has been shut down, including schools, universities, the subway system and many commercial centers. 
The city was used as a base by the terrorists who carried out the coordinated suicide bombings and gun attacks in which over 130 people were killed on November 13.
