Belgian police arrested 16 people during operations following the Nov. 13 Paris attacks but did not find Salah Abdeslam, the Brussels man suspected of playing a key role in the assault in France, the public prosecutor said early on Monday.
During one of 19 raids mounted across the capital, Brussels, police fired on a vehicle, but it was not clear if those inside were connected to those being sought, the prosecutor told a brief news conference.
On Sunday, Prime Minister Charles Michel, speaking after a meeting of security chiefs called to review the threat status, announced another day of lockdown in the capital for fear a new, Paris-style mass attack may be imminent.
