BRUSSELS – The latest on the deadly attacks in Paris and the heightened security in Europe (All times local):

9:30 a.m.

Brussels residents are waking up to largely empty streets as the city enters its second day under the highest threat level and the manhunt continues for a suspect missing since the Nov. 13 attacks in France.

Belgium's national Crisis Center on Saturday raised the threat alert in the Brussels region to Level 4, which indicates a "serious and immediate threat."

Subways and underground trams remain closed Sunday and officials recommended that sports competitions and all activities in public buildings should be cancelled and malls and commercial centers closed.

Belgian officials say the measures were recommended due to the extra security they would require. The country's Regional Security Council is set to meet Sunday afternoon to update any new measures needed.
