Brussels on lockdown as Paris attacks suspect on the run

Brussels began a third consecutive day in lockdown under a maximum terror alert Monday after Belgian police staged a series of raids but failed to find key Paris attacks suspect Salah Abdeslam.

In an unprecedented security operation for the European capital, schools, universities and the metro were shut in the face of what Prime Minister Charles Michel called a "serious and imminent" threat of attacks similar to those that killed 130 people in France.
